Abstract
Various transport measurements are performed to assess the alloying and siz e effects in sub-100 nm Bi1-xSbx (0 less than or equal tox less than or equ al to0.15) 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 nanowire s show interesting size-dependent behaviors similar to those in Bi nanowire s. (C) 2001 American Institute of Physics.
