FIR Emission and Absorption Due to Indirect Optical Transitions of Hot Electrons in GaAs/AlGaAs QW
Abstract
Far-infrared (lambda = from 70 to 300 micrometers) spontaneous emission and modulation of absorption under heating 2D-electrons in strong electric field applied along GaAs/AlGaAs quantum layers are observed and investigated. Emission and absorption of light are connected with indirect transitions of hot electrons in ground subband of quantum well. Hot electron temperature is determined from comparing experimental emission spectra and theoretical ones taking into account optical phonon, impurity and interface roughness scattering as well as electron-electron scattering.
