  • Abstract
    Optically pumped THz emission has been observed in a wide range of semiconductors, and this process is an important practical source of pulsed THz radiation for time-domain THz spectroscopy and THz imaging. We show that InAs quantum dots on GaAs can be used to significantly enhance THz emission compared with a bare GaAs surface.
