We report a novel measurement technique for the wide‐band determination of the frequency response of photodetectors. It is based upon the accurate measurement of the photocurrent noise spectra under illumination with a light‐emitting diode. The h

The band-gap renormalization at finite temperatures in quantum wells is calculated from the dynamical self energy. Sublevel formfactors and non-diagonal screening are taken into account. In order to compare with these calculations, the chemical poten
