Abstract
The metal-insulator transition (MIT) of VO2(M) nanorods was studied. It was found that there were two MITs in the differential scanning calorimetry (DSC) curves of the VO2(M) nanorods, one situated at low temperature from -3 oC to 19 oC and the other was at high temperature of 65-74 oC. The low temperature MIT was always accompanied with VO2(B) nanorods, and the high temperature MIT existed singly only in pure VO2(M) nanorods. The mechanisms of these two MITs were analyzed and discussed.
