Abstract

A concise numerical model, based on drift-diffusion equations and wave propagation in a multilayered medium, has been developed to investigate photodetectors composed of two-dimensional materials. Comparisons between the numerical results and experiments validate the precision of the proposed approach in calculating the quantum efficiency as a function of incident wavelength. The formulation also enables the calculation of advanced photodetector parameters such as phase noise and bandwidth.
