Abstract

The metal insulator transition (MIT) characteristics of macro-size single-domain VO2 crystal were investigated. At the MIT, the VO 2 crystal exhibited a rectangular shape hysteresis curve, a large change in resistance between the insulating and the metallic phases, in the order of ~105, and a small transition width (i.e. temperature difference before and after MIT) as small as 10-3°C. These MIT characteristics of the VO2 crystals are discussed in terms of phase boundary motion and the possibility of controlling the speed of the phase boundary, with change in size of crystal, is suggested.
