Physisorption of a CH3Cl molecule via changing the site and orientation of the molecule was studied on the Fe(100) surface using DFT. All reasonable molecular and dissociative adsorption routes of the CH3Cl molecule on the Fe(100) surface have been systematically investigated. Molecular adsorption was considered on four different surface sites with different orientations with Cl, C, and H atoms toward and away from the surface. Chemisorption was considered by decomposition of CH3Cl into a methyl (CH3) group and a Cl atom via a cleavage of the C–Cl bond and by decomposition into a CH2Cl group and a H atom via a cleavage one of the C–H bonds. Chemisorption produces a greater degree of bonding than physisorption.","PeriodicalId":11626,"journal":{"name":"E-journal of Surface Science and Nanotechnology","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135305552","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}

However, there is a lack of information available on the effect of an insulator dielectric passivation layer on the breakdown voltage (Vbr) of AlGaN/GaN HEMTs. This study utilizes technology computer aided design to investigate the impact of different insulator dielectric passivation layers, such as SiO2, SiN, Al2O3, and HfO2, on Vbr of AlGaN/GaN HEMTs. Furthermore, the study optimizes the parameters of the field plate length (LFP) and insulator thickness to maximize Vbr of AlGaN/GaN HEMTs. Results indicate that HEMTs with a field plate (FP-HEMTs) have greater Vbr than HEMTs without a field plate (N-HEMTs). With the optimized conditions of a 1.8 µm LFP and a 0.95 µm insulator thickness with HfO2 passivation, Vbr of 1120 V is achieved. The findings suggest that the field plate (FP) and passivation layer can significantly improve the efficiency and reliability of AlGaN/GaN HEMTs while the impact of AlGaN/GaN heterostructure parameters on Vbr is minimal.","PeriodicalId":11626,"journal":{"name":"E-journal of Surface Science and Nanotechnology","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135305556","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}
