Reliability assessment of high-power GaN-HEMT devices with different buffers under influence of gate bias and high-temperature tests
This study compares Vth-instability in D-mode MIS-HEMT devices between two epitaxial layers, AlN/AlGaN/GaN superlattice-W1, and three-step graded AlGaN-W2. Experimental results demonstrate that W1 exhibits ∼13% less Vth-instability compared to W2, with distinct degradation regions at specific voltag...
