Inhomogeneity model for anomalous Hall effects in n-type Hg sub(0.8)Cd sub(0.2)Te liquid-phase-epitaxy films

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) Hg sub(0.8)Cd sub(0.2)Te films. After establishing that surface effects are not the cause of the anomalies and that the authors' LPE films are indeed n type, they propose an inhomogenity model with a network of extended p-type inclusions in an n-type matrix. Good fits to the experimental data have been obtained by computer simulation based on this model.
