Abstract

The present understanding of the carrier transport properties in Hg-based super-lattices such as the HgTe-CdTe system is reviewed. Novel features in the calculated superlattice band structures and their implications for macroscopic transport properties are discussed. Nearly all of the main experimental results are qualitatively consistent with a large valence band offset, but are difficult to explain if the offset is small. The valence band offset controversy thus appears to have been largely resolved.

Although the direct energy gap is always negative for sufficiently thick wells, the valence band maximum can occur kx > 0 when dw is large, and under some circumstances the superlattice may remain semimetallic for all well thicknesses.+0+when+dw+is+large,+and+under+some+circumstances+the+superlattice+may+remain+semimetallic+for+all+well+thicknesses.>Google Scholar
