摘要:
Anomalous Hall effects, i.e., peaks in the temperature dependence of the Hall coefficient and Hall mobility, have been observed in liquid‐phase‐epitaxy (LPE) Hg0.8Cd0.2Te films. After establishing that surface effects are not the cause of the anomalies and that our LPE films are indeedntype, we propose an inhomogeneity model with a network of extendedp‐type inclusions in ann‐type matrix. Good fits to the experimental data have been obtained by computer simulation based on this model.
