Abstract
Antimony telluride (Sb2Te3) nanoplates of various thickness were grown by the vapor phase deposition method. The Hall resistance and magnetoresistance of the samples were measured in magnetic fields up to 9 T at temperatures from 2 to 300 K. Temperature dependence of the magnetoresistance and Hall resistance of the nanoplates shows a strong dependence on the thickness of the samples. Relatively thick samples show a nonlinear dependence of the Hall resistance on magnetic field. The measurement data are analyzed within the model of multi-channel transport. The difference in behavior is attributed to the existence of two channels of charge transfer with high and low mobility.
