摘要：

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