Abstract
Polarization analysis of optical emission from the electron gas in GaAs single quantum wells discriminates the separate contributions from spin-split electron states. In the extreme quantum limit, the vastly different electron populations of these two states allows the study of many-body phenomena in the presence of localization. Reduction in electron screening of the hole at =1 appears to cause energy shifts in narrow quantum wells, while electron-hole binding dominates in wider wells. Evidence of a technique probing the spin-configuration of fractional quantum Hall states is also presented.
