中文摘要

商用氮化镓(GaN)高电子迁移率晶体管在电力电子领域表现优于硅基器件,且具备抗辐射能力,是空间等严苛环境下高性能电力系统的关键候选者。然而,理解其在额定温度范围内的潜在失效机理对于确保系统可靠性至关重要。

English Abstract

Commercial gallium nitride (GaN) high-electron-mobility transistors used for power electronics applications show superior performance compared to silicon (Si)-based transistors. Combined with an increased radiation hardening properties, they are key candidates for high-performance power systems in a harsh environment, such as space. However, for this purpose, it is key to know the potential failur...
