Abstract
Electrical conductivity and Hall effect of Mnx Cd1−xSe have been measured from 40 to 300 K for the composition range 0<x≤0.30. The compositional dependence of the density‐of‐state mass of conduction band was obtained by fitting to the Hall‐coefficient data, a model based upon a parabolic conduction band and a single ionized donor level. A variational calculation of the electron mobility for Mnx Cd1−xSe was performed, taking as the limiting scattering mechanisms longitudinal‐optical‐phonon scattering, acoustic‐phonon scattering, piezoelectric scattering, and scattering by charged defects. The results of this calculation are in good agreement with the experiment.
