Improving breakdown voltage of double-channel E-mode AlGaN/GaN HEMTs using a double-gate structure
In this study, the characteristics of a double-channel AlGaN/GaN HEMT are improved. Firstly, depletion mode is changed to enhancement mode by changing the thickness of an AlGaN layer, implementing a p-doped region, and changing the material of buffer layer. Secondly, Al ratio in the upper AlGaN layer is optimized to improve the flatness of Gm-VGS curve so that the linearity is improved. Finally, breakdown voltage is increased by using a double-gate structure.
