At present, color centers in wide-bandgap semiconductors, such as the nitrogen-vacancy (NV) and silicon-vacancy (SiV) centers in diamond, are considered to be the most promising candidates for practical quantum information applications owing to their unique emission properties at room temperature. However, for practical reasons, single-photon sources should be pumped electrically, which is required for integrability, scalability, and energy efficiency. However, diamond and related wide-bandgap semiconductor materials are at the interface between insulators and semiconductors, which makes electrical excitation of color centers very challenging. Here, we report on our progress in the understanding of single-photon electroluminescence of color centers in diamond, discuss different factors affecting the brightness of these emitter under electrical excitation, and study how to improve the performance of electrically- pumped single-photon sources based on color centers in diamond.","PeriodicalId":405600,"journal":{"name":"PROCEEDINGS OF INTERNATIONAL CONGRESS ON GRAPHENE, 2D MATERIALS AND APPLICATIONS (2D MATERIALS 2019)","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126703732","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For the biosensing purpose, the graphene layers have to be uniform and have an accurately controlled thickness. Graphene quality may vary depending on the method of its production. Using Raman spectroscopy, an assessment was made of the quality and suitability of the use of CVD and exfoliated graphene for biosensors. The Raman spectra of graphene obtained by the chemical vapor deposition method were measured before and after transferring. We found that CVD graphene with single and bi-layer thickness has a uniform structure with lager area and a small number of defects. But the number of defects increases with an increase of the number of layers. Also, we found that for some samples with CVD graphene, sometimes it is difficult to determine the number of layers since the specific shape of the 2D peak is not always explicitly expressed. Furthermore, it was shown that the exfoliated graphene, although having fewer defects, have non-uniform structure, with smaller areas of monolayer graphene.","PeriodicalId":405600,"journal":{"name":"PROCEEDINGS OF INTERNATIONAL CONGRESS ON GRAPHENE, 2D MATERIALS AND APPLICATIONS (2D MATERIALS 2019)","volume":"337 10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123232198","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
