It is obtained that the solution, from the geometrical point of view, is equivalent to the one obtained for a dark energy fluid and a primordial magnetic field. It is determined that the function of the scalar field φ and the phase of the spinorial field G are proportional in all the values of t, which establishes a kind of exclusive property of the dark energy under the conditions of the interactive and self-consistent spinorial and scalar fields. It is concluded that the influence of the magnetic field under this spinorial and scalar fields is relevant for short periods.","PeriodicalId":127314,"journal":{"name":"Advanced Studies in Theoretical Physics","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132336862","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 device characteristics of the quantum dot are examined based on the exact potential and energy profile obtained from the solution of 3D Poisson and Schrodinger equations using Haar wavelets. The dark current is estimated by considering the quantum dot parameters, applied voltage and temperature. The physics based model is used to study the effect on the dark current resulting from changing the QD density, length of QD layer, number of QD layers and temperature. The results are validated with the existing experimental results that exhibit the strength of the proposed model. The physics based model is developed in general and can be used as a device for the photo detector and photovoltaic applications.","PeriodicalId":127314,"journal":{"name":"Advanced Studies in Theoretical Physics","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133952706","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}
