To explore the requiredcharacteristicsfor solar applications, we perform first-principles calculations based on DFT for Zn2V2O7structure. The results illustrate an upper valence band incorporating almost exclusively of O 2p orbitals, while V 3d states are the main constituents of the conduction band, with a moderate mobility of charge carriers. Furthermore, optical calculations display an indirect band gap with a value of 2.52 eV and a mean absorption coefficient about 7×104 cm-1 in the UV-Vis range.","PeriodicalId":6516,"journal":{"name":"2017 IEEE 7th International Conference Nanomaterials: Application & Properties (NAP)","volume":"11 1","pages":"03NE12-1-03NE12-4"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75742552","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}
