Abstract :
The magnetic field dependence of the THz radiation from InAs and InSb surfaces is studied up to 5 tesla. The intensity and spectra for horizontally and vertically polarized components of the THz radiation shows characteristic changes with magnetic field intensity. These results are discussed in relation to the photoexcited carrier dynamics.
