Firstly, we have opened a bandgap in both LB and HB zigzag silicene nanoribbon (ZSiNR) by hydrogen passivation and simulated for their transport properties. Further, we have doped the LB and HB ZSiNR structures by gallium (Ga) and arsenide (As) atoms in order to determine their changes in the transport properties. The results show that 4 atom width silicene nanoribbon shows a maximum band gap of 2.76 and 2.72 ˚A for LB-ZSiNR and HB-ZSiNR, respectively. The 2 atom doped ZSiNR shows good transport characteristics in the voltage range of 0.5 to 1.5 V in comparison with 4 and 6 atom doped models. The obtained results were validated by calculating the transmission spectrum and projected device density of states. It is believed that the modelled devices will find number of futuristic applications in the electronic industry.","PeriodicalId":18782,"journal":{"name":"Nanosystems: Physics, Chemistry, Mathematics","volume":"1 1","pages":""},"PeriodicalIF":0.9,"publicationDate":"2023-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81224718","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}

The electrical conductivity is calculated by numerical and approximate analytical methods in order to explain the process of ion transport.
