Summary:From far infrared magneto-optical absorption experiments done in n-type Hg 1−xZn xTeCdTe superlattices, the conduction band dispersion relations are obtained. Comparison with theoretical investigations evidences the semimetallic behavior of the studied superlattices at low temperatures and show that the valence band offset at each interface is certainly large (≈ 360 meV).
