The first one is based on the numerical solution of the Vlasov-Poisson equations using the finite volume method, and the second is based on a particle-in-cell approach in phase space. Both methods were tested on a one-dimensional vacuum diode. The calculated current-voltage characteristics of the diode are in good agreement with each other, and with space-charge limited currents, predicted by Child-Langmuir law. These methods allowed us to study near-emitter region considering electrons thermal velocity spread, and space charge cloud, and to calculate the cut off voltage. The advantages and disadvantages of both methods are also discussed.","PeriodicalId":277559,"journal":{"name":"2020 International Conference on Actual Problems of Electron Devices Engineering (APEDE)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115045118","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}
