GaN基欧姆接触及AlGaN/GaNHEMT器件研究的开题报告
摘要:
氮化镓(GaN)是一种新型的半导体材料,具有高电子流动度和高热稳定性,逐渐被应用于高功率、高频率和高温度电子器件领域。其中,GaN基欧姆接触技术是实现高性能GaN器件的关键。
本文将介绍本人团队在GaN基欧姆接触及AlGaN/GaNHEMT器件研究方面的计划与进展。首先,我们将介绍GaN材料及其物理特性,特别是其与欧姆接触相关的性质。然后,我们将重点介绍欧姆接触的背景、原理及其在GaN器件制备中的应用。接着,我们将介绍AlGaN/GaNHEMT器件的结构和工艺流程,以及欧姆接触和其他关键工艺对器件的影响。最后,我们将讨论我们计划采用的实验方案和后续的研究方向。
通过本研究,我们希望能够深入了解GaN欧姆接触技术,以及其在AlGaN/GaNHEMT器件制备中的应用。我们的研究成果将有助于推动GaN器件的发展和应用。
