摘要：

Negatively charged excitons (two electrons bound to one hole), X-, are identified for the first time in semiconductor quantum wells. The optical transition corresponding to creation of X- is identified approximately 3 meV below the free exciton line X in the magneto-transmission spectra of CdTe/Cd1-xZnxTe quantum well heterostructures in which a dilute electron gas has been produced either by optical excitation or by modulation doping.
