Abstract

This work presents a numerical investigation into the performance metrics of photodetectors made from monolayer MoS₂, a two-dimensional material with unique optoelectronic properties. The study introduces a one-dimensional drift-diffusion framework and wave propagation in layered media analysis. Results demonstrate a peak quantum efficiency at 561 nm, influenced by the substrate. The precision of the model validates its utility for characterizing MoS₂ photodetectors, emphasizing the importance of background inclusion in calculations. The efficiency of the computation makes the model suitable for in-depth device analyses and device design via numerical optimization.
