Kotel'nikov, I. and Shul'man, A. and Ganichev, Sergey and Varvanin, N. and Mayerhofer, B. and Prettl, Wilhelm (1996) Heating of two-dimensional electron gas and LO-phonons in delta-doped GaAs by far-infrared radiation. Solid State Communications 97 (10), pp. 827-832.
A change in the conductivity of the two-dimensional electron gas in δ-doped GaAs samples due to pulsed far-infrared laser irradiation has been detected. It is shown that the observed positive photoconductivity is caused by heating of 2D electrons. The energy loss of hot electrons is accomplished by scattering with nonequilibrium longitudinal optical (LO) phonons. An expression for the effective ...
