Terahertz emission and lifetime measurements of ionimplanted semiconductors: Experiment and simulation

Abstract:

The spectral width of terahertz emission from ion-implanted terahertz emitters increases with ion damage, owing to ultrafast carrier capture. Carrier dynamics simulations reinforce these findings. Optical-pump, terahertz-probe experiments confirm the subpicosecond lifetimes of these materials. © 2006 Optical Society of America.
