• Resumen

  • We have implemented a two‐dimensional (2D) time‐dependent hydrodynamic model suitable for studying III‐V heterostructural semiconductor devices. This we apply in simulating a heterojunction metal‐semiconductor‐metal (MSM) photodetector subject to pico‐second optical pulses. The inclusion of the energy balance equation introduces an additional time delay in the response of the detector, which is comparable to the energy relaxation time.
