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

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

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...
