By microstructuring the surface, we have fabricated LEDs with a beam divergence of less than 40 and a drastically increased quantum efficiency. We prove that surface plasmon excitation aid emission mechanism has the potential to overcome basic external quantum efficiency losses and to improve the performance of LEDs.","PeriodicalId":334101,"journal":{"name":"ESSDERC '90: 20th European Solid State Device Research Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1990-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133120009","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 complete design of a high voltage planar transistor (1500V) using a SIPOS layer on SiO2 film is extracted from bidimensional numerical simulations. The evolution of breakdown voltage BVcbo versus critical parameters as oxide thickness, field plate length and field plate-stop channel distance is calculated. A good agreement between theoretical and experimental results is obtained. The breakdown voltage achieved by the devices is near 90% of the ideal planar breakdown voltage without any damage for other electrical parameters.","PeriodicalId":334101,"journal":{"name":"ESSDERC '90: 20th European Solid State Device Research Conference","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1990-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127130564","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}
