Carrier transport properties ofphyphen;type Hg1minus;xCdxTe liquid phase epitaxial layers in the mixed conduction range

摘要

Galvanomagnetic measurements were made onphyphen;type Hg1minus;xCdxTe liquid phase epitaxial layers as a function of magnetic field and temperature. The dependence of the Hall coefficient on magnetic field was analyzed assuming mixed conduction of electrons and holes. The fitting of the theory to the experimental data permits determination of the concentration of holes and electrons and their mobilities over a range of temperatures. This leads to values of the intrinsic carrier concentration, which are in good agreement with those generated from theoretical calculations.
