ABSTRACT
Various transport measurements are performed to assess the alloying and size effects in sub-100 nm Bi[sub 1-x]Sb[sub x] (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 Bi[sub 1-x]Sb[sub x] systems. Magnetoresistance measurements of these Bi[sub 1-x]Sb[sub x] nanowires show interesting size-dependent behaviors similar to those in Bi nanowires. © 2001 American Institute of Physics.
