Abstract
Recently, contradicting results concerning magnetotransport experiments on n-InSb at liquid helium temperatures have been reported by various authors. The authors' experiments show that the assumption of the existence of a conducting surface layer due to soldering of tin contacts to the samples is not valid. Experiments on samples treated by careful etching procedures have proven the sign change of the Hall effect and the saturation of the transverse magnetoresistance to be bulk effects.Keywords
