OPTICAL SPECTROSCOPY OF GAAS IN THE EXTREME QUANTUM LIMIT - INTEGER AND FRACTIONAL QUANTUM HALL-EFFECT, AND ONSET OF THE ELECTRON SOLID
Our recent optical detection of the integer and fractional quantum Hall effects in GaAs, by intrinsic band-gap photoluminescence at dilution refrigerator temperatures, is reviewed. This work has been extended to the extreme quantum limit where a photoluminescence peak develops close to Landau level...
