OPTICAL TIME-OF-FLIGHT MEASUREMENT OF CARRIER DIFFUSION AND TRAPPING IN AN INGAAS/INP HETEROSTRUCTURE
We have measured the diffusion and trapping of photoexcited hot carriers in an InGaAs/InP heterostructure using an optical time-of-fight technique with picosecond time resolution. The ambipolar diffusivity is found to decrease by an order of magnitude between 4 K and room temperature, and the effici...
