Logarithmic behavior in a new two-dimensional metal: HgTe-CdTe superlattice

Abstract
The resistance of a HgTe-CdTe superlattice of layer thickness 110 Å/220 Å shows logarithmic behavior with respect to temperature below 30 K. The field-parallel and field-perpendicular magnetoresistance clearly distinguish between the orbital and spin-dependent scattering mechanisms, and confirm two-dimensional behavior.
