Abstract

IT-VT superlattices formed with CdTe and a zero-gap mercury based compound have been termed ''Type III" heterostructures. They can be either narrow band-gap semiconductors or semimetals depending on layer thicknesses and temperature. We shall report cyclotron resonance measurements on high electron mobility HgZnTe-CdTe and HgMnTe-CdTe superlattices grown by molecular beam epitaxy. The theoretical analysis of the data leads to an accurate determination of the electronic properties of these new infrared materials (superlattices bandgap as a function of the temperature temperature induced semimetal - semiconductor transition electron mass anisotropy exchange interaction in the diluted magnetic semiconductor superlattices. . . ).
