Simulate and analyze photodiodes using COMSOL Multiphysics
This study used COMSOL Multiphysics to simulate the working state of GaAs thin film based photodiodes under electromagnetic radiation with a wavelength of 875nm.Unlike experimental research on diode electronic devices,this work is based on the research idea of coupling light waves and electromagnetic fields,and establishes a model to meticulously calculate the electromagnetic field strength at various locations inside semiconductor materials.By calculation,the electric field strength fluctuates within the range of 20450～20500v/m,and a voltage drop of 3.96V is formed at both ends of the diode.
