摘要：
Gate-all-around nanowire junctionless transistor with an auxiliary gate (AG-GAAJLT) is proposed to restrain the band-to-band tunneling (BTBT) resulted in off-state leakage current in junctionless transistor. The device is investigated through three-dimensional (3D) numerical simulations. Results show that the AG-GAAJLT has seven orders of magnitude lower off-state current compared with the conventional gate-all-around junctionless transistor (C-GAAJLT). The effects of auxiliary gate voltage (V-AG) and distance between control gate and auxiliary gate (d(G-AG)) are studied, and the optimizations of V-AG and d(G-AG) are presented. This work provides a new method to solve the BTBT in GAAJLT.
