MATLAB-Based Simulator for Metal-Insulator-Metal Diodes and Transistors

Metal-Insulator-Metal diodes are heavily used in rectification antenna, Rectenna, applications to harvest power from incident radiation. Modelling of such devices is important to acquire fast-switching and low-power devices. In this work, we provide a numerical simulation tool to model the current-voltage characteristics of these devices and study the impact of design variation on performance metrics like resistivity, responsivity, asymmetry and nonlinearity of the current-voltage characteristics. The simulator is based on MATLAB environment with aid finite-element solver and several tunneling current approximations, mainly transmission-line method.
