Anisotropy in the Electrical Resistivity of Vanadium Dioxide Single Crystals

Abstract
Electrical resistivity of vanadium dioxide single crystals undoped and iron‐doped was determined as a function of temperature around the transition temperature in the a monoclinic and a perpendicular directions. Results of this experiment indicated a greater resistivity in the a perpendicular direction than in the a parallel direction for both the doped and the undoped crystals. The appearance of anisotropy is in agreement with Goodenough's explanation for the mechanism of electrical conductivity in this phase.
