Abstract
Weak field Hall effect measurements between 34 and 300 K were applied to three PbSe/PbEuSe ( E g[PbEuSe] = 440 meV at 300 K) MQW samples on KCl. By calculating the quasi-Fermi energy levels the temperature dependent band-edge offsets were determined. The valence band offset ΔE rmv was found to be 65 meV at 34 K with a positive temperature coefficient of 0.68 meV/K. Thus ΔE v = 43 + 0.68 T (meV) is suggested.
