abstract = "We report optical, structural, and electrical properties of VO2 on sapphire substrates with c-, m- and r- orientations with identical growth conditions. XRD data show that VO2 orientation depends on the substrate orientation. Based on temperature-dependent resistivity measurements, metal-insulator phase transition (MIT) temperature, TMIT, depends on the VO2 orientation due, primarily, to stress. The energy gap E g is observed to gradually red shift as temperature increases before collapsing to Eg ≈ O eV at temperatures below TMIT.",
