ABSTRACT
The relation between the value of the valence-band offset Vp at a HgTe/CdTe heterojunction and the energy difference ΔE between the first heavy hole subband and the first light hole subband at the Brillouin zone center of a HgTe/CdTe superlattice is examined theoretically. The theoretical values of ΔE are compared with those obtained from far-infrared magneto-optical measurements for two HgTe/CdTe superlattices. A single value of Vp =63±5 meV is found which fits the experimental values of ΔE for both superlattices.

    Superlattices have drawn considerable attention in the recent years. In this work, the behaviour of polaritons in a quantum wire superlattice is analysed both at the brillouin zone edge and at centre of the brillouin zone using LiNbO3/LiTaO3 as an example. The significance of the polariton modes...
