Theoretical Analysis of Low-Threshold Avalanche Effect in WSe₂ Stepwise van-der-Waals Homojunction Photodiodes

In this work, we report simulation-assisted analysis of a room-temperature (300 K) low-threshold avalanche photodiode (APD) based on a WSe₂ homojunction. Device simulations were conducted using a two-band model and the Chynoweth formalism for impact ionization, with material parameters ex...
