Abstract

The University of California at Santa Barbara free‐electron laser was used to investigate the kinetics of electrons bound to shallow donors in n‐GaAs by saturation spectroscopy. The resonant photothermal conductivity arising from 1s–2p+ shallow donor excitations in a magnetic field was measured at intensities greatly exceeding that of earlier investigations and saturation of bound‐to‐free ...
