A numerical study of RF performance for a junctionless vertical MOSFET

Abstract

In this paper, for the first time, we demonstrate the radio frequency (RF) performance of a junctionless vertical MOSFET (JLVMOS). According to the numerical simulation results, the JLVMOS can obtain higher gm, lower gd, in comparison to a junctionless planar SOI MOSFET. This because the vertical double-gate (DG) scheme truly helps to increase the gate controllability over the channel region, resulting in reduced short-channel effects (SCEs).
