Simulation of THz generation and propagation from photo-Dember emitters

Simulation of THz generation and propagation from photo-Dember emitters
Simulation of THz generation and propagation from photo-Dember emitters
We demonstrate a simulation of lateral photo- Dember THz emitters in 2D using the drift diffusion equation coupled to a finite differences time domain (FDTD) model with far-field algorithm. We show that the dynamics of the system are more dependent on the currents travelling perpendicular to the semiconductor surface, as opposed to just the lateral currents as previously thought.

Abstract

We demonstrate a simulation of lateral photo- Dember THz emitters in 2D using the drift diffusion equation coupled to a finite differences time domain (FDTD) model with far-field algorithm. We show that the dynamics of the system are more dependent on the currents travelling perpendicular to the semiconductor surface, as opposed to just the lateral currents as previously thought.
