Transport properties of Bi1−xSbx alloy nanowires synthesized by pressure injection

Abstract
Various transport measurements are performed to assess the alloying and size effects in sub-100 nm Bi1−xSbx (0⩽x⩽0.15) nanowires. Temperature-dependent resistance measurements exhibit non-monotonic trends as x increases, and a theoretical model is presented to explain the features which are related to the unusual band structure of Bi1−xSbx systems. Magnetoresistance measurements of these Bi1−xSbx nanowires show interesting size-dependent behaviors similar to those in Bi nanowires.
