Abstract
Low-temperature Shubnikov-de Haas (SdH) oscillations and the Hall effect have been studied on a HgTe/CdTe superlattice grown by laser molecular-beam epitaxy. The results indicate that three subbands in the quantum well contribute to the conductivity. A line-shape fit of the SdH data also indicates that the intermediate SdH component has an electron effective-mass ratio which is five times larger than the mass ratio of the lower-frequency SdH component.Keywords
