Simulating Nanoscale Vacuum Channel Transistor Arrays in Ltspice Utilizing an Empirical Warm-Beam Child-Langmuir Model

Abstract

Large nanoscale vacuum channel transistor (NVCT) arrays are implemented in LTspice. An empirical warm-beam Child-Langmuir (CL) model is used to determine space charge limiting effects on transmitted current. The LTspice NVCT model is simulated in a Colpitts oscillator circuit. These results are compared to an LTspice NVCT model based on experimental measurements of a particular physical device [1]. The warm-beam CL model is used to demonstrate rapid exploration of different array and circuit parameters.
