WebThe dynamic ON-resistance (Ron) of p-GaN HEMTs was reduced using the dual field plate (FP) structure combined with the source field plate (S-FP) and gate field plate (G-FP). The electric field redistribution at the gate edge reduces the electron trapping during the high voltage blocking, avoiding the Ron increase after the device switching on. The devices … WebSurge-energy and overvoltage ruggedness of power devices are desired in many power applications. For the GaN high-electron-mobility transistor (HEMT), a device without …

Overvoltage Robustness of p-Gate GaN HEMTs in High

WebJul 14, 2024 · p-type doped GaN layer is introduced under the gate metal [6-11]. To reduce gate leakage, the metal/p-GaN interface is typically of Schottky type. Recently reports investigated the effects of drain bias stress on the threshold voltage V TH and ON-resistance in p-GaN gate HEMTs. Specifically, it was observed that a drain bias stress WebThe breakdown voltage and frequency characteristics of HEMTs are typically traded off. However, the proposed III-Nitride nano-HEMT grown over β-Ga 2 O 3 substrate … WebSep 1, 2016 · 1. Introduction. GaN-HEMTs can realize high-power-density operation with low power loss in RF and power electronics systems. This is because of high carrier mobility of the two-dimensional electron gas (2DEG) and high breakdown voltage because of large critical electric field [1].Recent demonstrations show that GaN-HEMTs can attain … bk precision 2530b
