The observation of the integral quantum Hall effect in narrow band-gap PbTe/Pb1-xEuxTe single and multi quantum well structures grown by molecular beam epitaxy on BaF2 substrates is reported. The transport data prove two-dimensional electron confinement. Measurements show the existence of a parallel 3D conduction channel, due primarily to un-depleted regions of the barrier and buffer material, Pb1-xEuxTe. Repeated thermal cycling causes an increase in carrier density and a degradation in transport due to dislocations induced by thermal expansion coefficient mismatch between the substrate and IV-VI compound layers.
