First Demonstration of Optically-Controlled Vertical GaN finFET for Power Applications

Jung-Han Hsia,

Abstract: In this work, we propose a novel optically-controlled vertical GaN finFET directly triggered by low-power ultraviolet (UV) illumination. The proposed device consists of a normally-off, vertical GaN finFET with an optically transparent illumination window. Electron-hole pairs are generated in the depleted fin channel upon 365 nm illumination to turn on the device. The operating principle of optically-controlled, vertical finFETs was first confirmed through simulations where 5 orders of magnitude on-off current … Show more
