Abstract
Teraheratz bandwidth electromagnetic radiation can be optically induced from semiconductor surfaces.1 This diffraction-limited electromagnetic beam propagates in free space and can be optically steerable by varying the incident angle of the laser beam. The waveform of the radiated field depends on the impurity concentration, carrier mobility, and built-in field near the surface.
