Abstract

In this work, we utilize a coupled system to describe the carrier density in the Metal-Semiconductor Field-Effect Transistor (MESFET) device. To identify the depletion layer in this semiconductor, we define a cost functional $J$, and then use it to derive the shape optimization problem, for which we prove the existence of a solution. We develop an approach to solve this optimization problem based on the finite element method with particle swarm optimization. Finally, we present several numerical examples to demonstrate the robustness of our proposed algorithm in identifying the depletion layer in the MESFET device.
