Accuracy balancing for the simulation of gate-all-around junctionless nanowire transistors using discrete Wigner transport equation

Abstract

We report the application of the discrete Wigner transport equation to the simulation of gate-all-around junctionless nanowire transistors (JLNWTs). We show that unphysical simulation results are obtained unless we pay attention to the accuracy balancing problem. An empirical criterion based on the subthreshold swing of the JLNWT is proposed for the accuracy balancing. Using this criterion, we investigate the characteristics of JLNWTs with the quantum effect fully considered.
