δ掺杂AlGaAs/GaAs HEMT的二维量子模型

open access: yes, 1997
首次建立了δ掺杂AlGaAs/GaAs高电子迁移率晶体管(HEMT)的二维量子模型,这种模型考虑了HEMT器件沟道中二维电子气的量子特性。根据这个模型,应用二维数值模拟方法和自洽求解薛定谔方程和泊松方程获得了器件沟道中的二维电子浓度,同时也得到了器件沟道中的横向电场分布和横向电流密度,模拟结果表明二维电子气主要分布在异质结GaAs一侧量子阱中 ...

增强型AlGaN/GaN HEMT器件工艺的研究进展

open access: yes, 2011
随着高压开关和高速射频电路的发展,增强型GaN基高电子迁移率晶体管(HEMT)成为该领域内的研究热点。增强型GaN基HEMT只有在加正栅压才有工作电流,可以大大拓展该器件在低功耗数字电路中的应用。近年来,国内外对增强型GaN基HEMT阈值电压的研究主要集中以下两个方面: 在材料生长方面,通过生长薄势垒、降低Al组分、生长无极化电荷的 AIGaN/GaN异质材料、生长InGaN或p-GaN盖帽层,来控制二维电子气浓度; 在器件工艺方面,采用高功函数金属、MIS结构、刻蚀凹栅、F基等离子体处理 ...
