Abstract
We have studied the electroreflectance and photoreflectance spectra from a pseudomorphic Ga0.78Al0.22As/In0.21Ga0.79As/GaAs modulation‐doped quantum well (MDQW) structure in the temperature range 79<TNs), as well as other important parameters of the structure. Our value for Ns is in good agreement with a Hall measurement.Keywords
