This method enables the calculation of carrier concentration, carrier mobility and entropy by integrations in the space of wave vector. In this same way the electrical current density and density of entropy currents are determined. The influence of quasi-Fermi energy gradients and the gradient of temperature on the physical parameters of the heterostructure is taken into account.","PeriodicalId":425705,"journal":{"name":"2016 International Conference on Numerical Simulation of Optoelectronic Devices (NUSOD)","volume":"439 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132751070","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}
