Abstract :
Summary form only given.The ability to generate ultrashort pulses of THz radiation has made time-domain spectroscopy possible at THz frequencies. Until now, this technique has only been applied to spectroscopy of free photoexcited carriers. Here, we present a time-resolved study of intersubband transitions of extrinsic electrons in quantum wells (QWs).
