Magnetotransport near the metal-insulator transition in Cd0.6Mn0.4Se
Abstract
A T-1/2 dependence of the log of the resistivity on temperature has been observed for Cd0.6Mn0.4Se in the insulating phase near the metal-insulator transition. The results are consistent with the theory of Efros and Shklovskii for variable range hopping modified by the electron-electron interaction. Estimates for the Thomas-Fermi screening length derived from these data is found to increase with magnetic field. © 1986 The American Physical Society.
