WebAug 23, 2016 · Abstract. The high efficiency and power density of AlGaN/GaN high electron mobility transistors (HEMTs) can be limited by parasitic charge trapping at sites on the semiconductor surface. Trapped electrons at the surface deplete the two-dimensional electron gas (2DEG), resulting in effects known as current collapse, increased dynamic … Web楼主的提问，就有点带偏别人的感觉，或者，你已经被别人带偏了。首先，半导体是一门非常专业的学科，半导体器件仿真肯定需要专业的仿真软件，而通用CAE类的软件是无法解决大多数技术细节问题的，comsol， ansys，abaqus,就是通用CAE WebSep 22, 2024 · GaN HEMTs are field-effect transistors (FETs) that can switch faster than silicon power transistors. This feature, combined with GaN HEMTs' small footprint, allows the devices to be more energy-efficient while creating more space for external components. These devices can also operate in higher voltages. Simplified GaN HEMT structure. electroline south africa
