AlGaN/GaN, HEMTs, hetero-structure,Wide band gap material, Silvaco.
AlGaN/GaN High Electron Mobility Transistors (HEMTs) have wide bandgap and therefore, it offers to be used at higher output power than other III-V semiconductor devices. As compared to conventional semiconductor materials, these wide bandgap materials have several modeling constraints and fabrication challenges. This paper models the complex fabrication process flow of HEMT device in simpler way that will be used at high power applications. In addition, Choice of materials for each layer with layered structure is also presented. A comparative study in between conventional Si based transistor and HEMT is also included here.
