Abstract

A terahertz (THz) field may he generated at the surface of a semiconductor by surface field photoconduction (SEP). In this process, photogenerated carriers are accelerated by the built-in surface field within the depletion region and their coherent motion results in the cooperative emission of THz radiation. A significant enhancement in the THz power generated by SFP has been observed when a magnetic field is applied to InAs.1,2
