Recent studies have proposed that W vacancies are the predominant point defect in 2D WSe2, in contrast to theoretical studies, which predict that chalcogen vacancies are the most likely intrinsic point defects in transition metal dichalcogenide semiconductors. We show using first-principles calculations, scanning tunneling microscopy (STM), and scanning transmission electron microscopy experiments that W vacancies are not present in our CVD-grown 2D WSe2. We predict that O-passivated Se vacancies (OSe) and O interstitials (Oins) are present in 2D WSe2, because of facile O2 dissociation at Se vacancies or due to the presence of WO3 precursors in CVD growth. These defects give STM images in good agreement with experiment. The optical properties of point defects in 2D WSe2 are important because single-photon emission (SPE) from 2D WSe2 has been observed experimentally. While strain gradients funnel the exciton in real space, point defects are necessary for the localization of the exciton at length scales that enable photons to be emitted one at a time. Using state-of-the-art GWBethe-Salpeter-equation calculations, we predict that only Oins defects give localized excitons within the energy range of SPE in previous experiments, making them a likely source of previously observed SPE. No other point defects (OSe, Se vacancies, W vacancies, and SeW antisites) give localized excitons in the same energy range.

The emergence of single quantum emitters in layered transition metal dichalcogenide semiconductors offers new opportunities to construct a scalable quantum architecture.

We intend this tutorial to serve as a useful resource for new and experienced researchers aiming to produce reliable and high-quality photophysical data.", "publicationTitle": "Dalton Transactions", "publisher": "", "place": "", "date": "2025", "volume": "54", "issue": "44", "section": "", "partNumber": "", "partTitle": "", "pages": "16268-16284", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "Dalton Trans.", "DOI": "10.1039/D5DT02095F", "citationKey": "", "url": "https://xlink.rsc.org/?DOI=D5DT02095F", "accessDate": "2026-03-03T06:37:08Z", "PMID": "", "PMCID": "", "ISSN": "1477-9226, 1477-9234", "archive": "", "archiveLocation": "", "shortTitle": "", "language": "en", "libraryCatalog": "DOI.org (Crossref)", "callNumber": "", "rights": "", "extra": "", "tags": [], "collections": [ "6LMGISEV" ], "relations": {}, "dateAdded": "2026-03-03T06:37:08Z", "dateModified": "2026-03-03T06:37:08Z" } }, { "key": "WJ4PXJ4D", "version": 5738, "library": { "type": "group", "id": 58653, "name": "[ARON SKKU]", "links": { "alternate": { "href": "https://www.zotero.org/groups/aron_skku", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/58653/items/WJ4PXJ4D", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/aron_skku/items/WJ4PXJ4D", "type": "text/html" }, "up": { "href": "https://api.zotero.org/groups/58653/items/7Q7KYKPW", "type": "application/json" } }, "meta": { "createdByUser": { "id": 69489, "username": "yjsong", "name": "Young Jae Song (ARON)", "links": { "alternate": { "href": "https://www.zotero.org/yjsong", "type": "text/html" } } }, "numChildren": 0 }, "data": { "key": "WJ4PXJ4D", "version": 5738, "parentItem": "7Q7KYKPW", "itemType": "attachment", "linkMode": "imported_file", "title": "PDF", "accessDate": "", "url": "", "note": "", "contentType": "application/pdf", "charset": "", "filename": "Dang 및 Teets - 2025 - A practical guide to measuring and reporting photophysical data.pdf", "md5": "4e1f5a287aeab67f941ee4d9dfc92e28", "mtime": 1772519828573, "tags": [], "relations": {}, "dateAdded": "2026-03-03T06:37:02Z", "dateModified": "2026-03-03T06:37:08Z" } }, { "key": "PENNWV3B", "version": 5734, "library": { "type": "group", "id": 58653, "name": "[ARON SKKU]", "links": { "alternate": { "href": "https://www.zotero.org/groups/aron_skku", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/58653/items/PENNWV3B", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/aron_skku/items/PENNWV3B", "type": "text/html" }, "up": { "href": "https://api.zotero.org/groups/58653/items/VI6K7W4V", "type": "application/json" } }, "meta": { "createdByUser": { "id": 69489, "username": "yjsong", "name": "Young Jae Song (ARON)", "links": { "alternate": { "href": "https://www.zotero.org/yjsong", "type": "text/html" } } }, "numChildren": 0 }, "data": { "key": "PENNWV3B", "version": 5734, "parentItem": "VI6K7W4V", "itemType": "attachment", "linkMode": "imported_file", "title": "PDF", "accessDate": "", "url": "", "note": "", "contentType": "application/pdf", "charset": "", "filename": "Dunklin 등 - 2020 - Plasmonic Hot Hole Transfer in Gold Nanoparticle-Decorated Transition Metal Dichalcogenide Nanosheet.pdf", "md5": "24d20528149d5d8270a6973729d83cfe", "mtime": 1771826973962, "tags": [], "relations": {}, "dateAdded": "2026-02-23T06:09:28Z", "dateModified": "2026-02-23T06:09:34Z" } }, { "key": "VI6K7W4V", "version": 5734, "library": { "type": "group", "id": 58653, "name": "[ARON SKKU]", "links": { "alternate": { "href": "https://www.zotero.org/groups/aron_skku", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/58653/items/VI6K7W4V", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/aron_skku/items/VI6K7W4V", "type": "text/html" } }, "meta": { "createdByUser": { "id": 69489, "username": "yjsong", "name": "Young Jae Song (ARON)", "links": { "alternate": { "href": "https://www.zotero.org/yjsong", "type": "text/html" } } }, "creatorSummary": "Dunklin et al.", "parsedDate": "2020-01-15", "numChildren": 1 }, "data": { "key": "VI6K7W4V", "version": 5734, "itemType": "journalArticle", "title": "Plasmonic Hot Hole Transfer in Gold Nanoparticle-Decorated Transition Metal Dichalcogenide Nanosheets", "creators": [ { "creatorType": "author", "firstName": "Jeremy R.", "lastName": "Dunklin" }, { "creatorType": "author", "firstName": "Aaron H.", "lastName": "Rose" }, { "creatorType": "author", "firstName": "Hanyu", "lastName": "Zhang" }, { "creatorType": "author", "firstName": "Elisa M.", "lastName": "Miller" }, { "creatorType": "author", "firstName": "Jao", "lastName": "Van De Lagemaat" } ], "abstractNote": "This work studies photogenerated carrier dynamics in gold nanoparticle (AuNP)-decorated mono- to few-layer transition metal dichalcogenide (TMD) nanosheets using transient absorption spectroscopy (TA). TA unveiled the presence of a long-lived photoinduced absorption (PIA) feature in both MoSe2 and WSe2 decorated with covalently bound AuNPs. This long-lived PIA feature emerges only from direct Au interband excitation in AuNP-decorated MoSe2 and WSe2; it does not manifest from intraband excitation nor in AuNP-decorated MoS2 or WS2. Based on X-ray/ultraviolet photoelectron spectroscopy and previous theoretical studies, it is proposed that this PIA signature arises from hot hole transfer from the AuNP to the adjacent TMD, producing a charge-separated state. This suggests charge separation at the metal− semiconductor interface may be used to extend the lifetime of interband excitation generated hot holes. This development could represent an important advance in harnessing plasmonic dissipation pathways to generate long-lived carriers suited for solardriven light harvesting and catalysis.", "publicationTitle": "ACS Photonics", "publisher": "", "place": "", "date": "2020-01-15", "volume": "7", "issue": "1", "section": "", "partNumber": "", "partTitle": "", "pages": "197-202", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "ACS Photonics", "DOI": "10.1021/acsphotonics.9b01393", "citationKey": "", "url": "https://pubs.acs.org/doi/10.1021/acsphotonics.9b01393", "accessDate": "2026-02-23T06:09:33Z", "PMID": "", "PMCID": "", "ISSN": "2330-4022, 2330-4022", "archive": "", "archiveLocation": "", "shortTitle": "", "language": "en", "libraryCatalog": "DOI.org (Crossref)", "callNumber": "", "rights": "https://doi.org/10.15223/policy-029", "extra": "", "tags": [], "collections": [ "6LMGISEV" ], "relations": {}, "dateAdded": "2026-02-23T06:09:33Z", "dateModified": "2026-02-23T06:09:33Z" } }, { "key": "M58EFVAN", "version": 5730, "library": { "type": "group", "id": 58653, "name": "[ARON SKKU]", "links": { "alternate": { "href": "https://www.zotero.org/groups/aron_skku", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/58653/items/M58EFVAN", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/aron_skku/items/M58EFVAN", "type": "text/html" }, "up": { "href": "https://api.zotero.org/groups/58653/items/QW93MB8D", "type": "application/json" } }, "meta": { "createdByUser": { "id": 69489, "username": "yjsong", "name": "Young Jae Song (ARON)", "links": { "alternate": { "href": "https://www.zotero.org/yjsong", "type": "text/html" } } }, "numChildren": 0 }, "data": { "key": "M58EFVAN", "version": 5730, "parentItem": "QW93MB8D", "itemType": "attachment", "linkMode": "imported_file", "title": "PDF", "accessDate": "", "url": "", "note": "", "contentType": "application/pdf", "charset": "", "filename": "Verma 등 -

PiFM utilizes the non-propagating, enhanced near field at the apex of a sharp tip to locally induce a polarization in the sample, which in turn produces an additional force acting on the cantilevered tip. This photo-induced force, though in the pN range or less, can be extracted from the oscillation properties of the cantilever, thus enabling the generation of photo-induced force maps. Since its inception in 2010, the PiFM technique has grown into a useful nano-spectrocopic tool that has expanded its reach in terms of imaging capabilities and applications. In this review, we present various technical implementations of the PiFM approach. In addition, we discuss the physical origin of the PiFM signal, highlighting the contributions from dipole–dipole forces as well as forces that derive from photo-thermal processes.", "publicationTitle": "Chemical Society Reviews", "publisher": "", "place": "", "date": "2022", "volume": "51", "issue": "11", "section": "", "partNumber": "", "partTitle": "", "pages": "4208-4222", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "Chem.

Despite its prevalence, the photothermal effect in light-absorbing nanoparticles has typically been assessed using bulk measurements, neglecting near-field effects. Beyond standard imaging and therapeutic uses, nanosecond-transient photothermal effects have been harnessed for bacterial inactivation, neural stimulation, drug delivery, and chemical synthesis. While scanning probe microscopy and electron microscopy offer single-particle imaging of photothermal fields, their slow speed limits observations to milliseconds or seconds, preventing nanoscale dynamic investigations. Here, we introduce decoupled optical force nanoscopy (Dofn), enabling nanometer-scale mapping of photothermal forces by exploiting unique phase responses to temporal modulation. We employ the photothermal effect’s back-action to distinguish various time frames within a modulation period. This allows us to capture the dynamic photothermal process of a single gold nanorod in the nanosecond range, providing insights into non-stationary thermal diffusion at the nanoscale.", "publicationTitle": "Nature Communications", "publisher": "", "place": "", "date": "2023-11-10", "volume": "14", "issue": "1", "section": "", "partNumber": "", "partTitle": "", "pages": "7267", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "Nat Commun", "DOI": "10.1038/s41467-023-42666-9", "citationKey": "", "url": "https://www.nature.com/articles/s41467-023-42666-9", "accessDate": "2026-02-12T04:44:33Z", "PMID": "", "PMCID": "", "ISSN": "2041-1723", "archive": "", "archiveLocation": "", "shortTitle": "", "language": "en", "libraryCatalog": "DOI.org (Crossref)", "callNumber": "", "rights": "", "extra": "", "tags": [], "collections": [ "6LMGISEV" ], "relations": {}, "dateAdded": "2026-02-12T04:44:33Z", "dateModified": "2026-02-12T04:44:33Z" } } ]
