Zusammenfassung This paper reports on the normally off GaN vertical MOSFETs based on nanowires (NWs) with an inverted p-GaN channel and a wrap around-gate structure for the first time. Both the inductively coupled plasma dry reactive-ion etching and wet-chemical etching were employed to fabricate the vertically aligned GaN NWs from epitaxial thin films with a specified doping profile. During the wet etching, the influence of p-doping on the NW morphology was investigated, and the results could be explained by the proposed model. In comparison with the other c-axis NW transistors, an enhancement-mode (E-mode) operation with a superior threshold voltage (Vth) of 2.5 V has been reached in the fabricated GaN MOSFETs. Furthermore, a high-driving current density of 101 kA/cm2 as well as a high-current on and off ratio of 109 was obtained in the NWs, predicting a potential approach toward the future GaN electronics with vertical and smart architecture.
