Abstract

In this paper, we report the investigation of the thermal enhancement and the behaviour of GaN Schottky diodes grown by metal-organic chemical vapor deposition (MOCVD) on sapphire substrates for RF power applications and their potential to operate under extreme temperatures. The Schottky barrier diodes show a Schottky barrier height (ϕ_B) close to 0.93 eV and an ideality factor (η) near unity, with 1.03. Pt/Au anodes annealed at 500°C and 600°C show an improvement in the electrical characteristics and a breakdown voltage as high as 130 V for a drift layer thickness of 1 µm and doping of 10¹⁶ cm⁻³.

600°C退火GaN肖特基二极管的热增强，用于高功率和高温射频应用

在本文中，我们报告了在蓝宝石衬底上通过金属有机化学气相沉积（MOCVD）生长GaN肖特基二极管的热增强和行为的研究，以及它们在极端温度下工作的潜力。肖特基势垒二极管的肖特基势垒高度（ϕB）接近0.93 eV，理想因数（η）接近1，为1.03。在500°C和600°C退火的Pt/Au阳极，在漂移层厚度为1 μ m、掺杂量为1016 cm−3的情况下，电特性得到改善，击穿电压高达130 V。
