Congratulations to Yigit Aytac for successfully defending his PhD dissertation on "Time-Resolved Measurements of Charge Carrier Dynamics in MWIR to LWIR InAs/InAsSb Superlattices."

"Yigit’s dissertation focused on measurements and analyses of electron-hole recombination and transport in optically excited, narrow-bandgap semiconductors designed for the next generation of infrared detectors. By analyzing the recombination as a function of time, temperature and optically injected electron-hole density, Yigit was able to separately measure the Shockley-Read-Hall, radiative, and Auger recombination processes. His measurements further identified a mid-band-gap defect state in InAs/InAsSb superlattices that controls recombination under the conditions of low light levels typical for semiconductor detectors. Yigit’s research was funded by the National Reconnaissance Office and was conducted in collaboration with researchers at Sandia National Laboratories."
