Abstract

Epitaxial thin films of vanadium dioxide (VO₂) have been grown on TiO₂ (001) and (110) substrates and the effect of uniaxial stress along the c-axis on the metal-insulator transition (MIT) of VO₂ has been studied. A large reduction in the transition temperature T_MI from 341 K for a single crystal to 300 K has been observed in the film on TiO₂ (001) where the c-axis length is compressed owing to an epitaxial stress, while the T_MI has been increased to 369 K in the film on TiO₂ (110) where the c-axis length is expanded. The correlation between the c-axis length and T_MI is suggested: the shorter c-axis length results in the lower T_MI.
