It is important to keep the well known qualitative properties of the Scharfetter-Gummel finite volume scheme, like positivity of solutions, dissipativity and consistency with thermodynamic equilibrium. A proper generalization to general statistical distribution functions is a topic of current research. The paper presents different state-of-the-art approaches to solve this problem. Their issues and advantages are discussed, and their practical performance is evaluated for real device structures.","PeriodicalId":114800,"journal":{"name":"Numerical Simulation of Optoelectronic Devices, 2014","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117354859","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}

Among the competitive materials and theoretical predictions favoring type-II superlattices (T2SLs) InAs/GaSb, HgCdTe has been still considered as the leader in terms of the fundamental parameters. The size, weight, power consumption and multispectral response of the infrared detection system play decisive role in fabrication of the higher operation temperature detectors. Several strategies have been implemented to improve the performance at elevated temperatures. The most efficient and used in HgCdTe technology are: non-equilibrium architectures and currently an idea of the barrier detectors. In this paper we present the comparison and short review of the nBnn and pBpp (Bn and Bp stands for n/p-type barrier) HgCdTe photodetectors.","PeriodicalId":114800,"journal":{"name":"Numerical Simulation of Optoelectronic Devices, 2014","volume":"132 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121363281","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}
