Abstract :
We study the emission mechanisms of THz radiation from InAs nanowires (NWs) using femtosecond infrared (IR) pump beam and THz probe in a time-resolved reflection geometry setup at room temperature. We compare the spectra of InAs NWs with that of a p-InAs crystal which is standard THz emitter.
