二氧化钒因其具有金属—绝缘体转变的相变性质 ,引起了广泛的重视。人们深入地研究了这种材料的相变特性 ,发现该材料在单晶状态 ,通过 68℃的相变点时 ,将发生 4～ 5数量级的电阻率突变 ,同时伴随明显的光学通过率突变 :由低温向高温转变的过程中 ,光学通过率 (尤其是在红外和 Vanadium dioxide has attracted a great deal of attention due to its phase-change property of metal-insulator transition. The phase transition characteristics of this material have been studied in depth and it has been found that when the material passes through the transformation point of 68 ° C in the single crystal state, a resistivity mutation of the order of 4 to 5 occurs with a sudden change in the optical transmittance: During the transition from low temperature to high temperature, the optical transmission rate (especially in infrared and infrared)
