What is Vanadium(Iv) Oxide Cas 12036-21-4?

Vanadium dioxide (VO2) is a strongly correlated electron system binary oxide. Due to the strong interactions between its internal electrons, orbitals, lattice, and spin, changes in local electrons and crystal structure caused by small external stimuli can induce VO2 to undergo reversible metal transformation. The crystal structure, resistance, infrared transmittance, refractive index and magnetic susceptibility of VO2 change dramatically. It is precisely because of the phase transition temperature near room temperature and the sudden changes in physical and chemical properties before and after the phase transition that VO2 has a very broad application prospect in electronics, military, daily life, and other fields.

Application

1.The application scope includes intelligent energy-saving windows, target camouflage, thermal rectification, RF switches, resonators, drivers, temperature sensitive devices, and field emission devices;
2.Photoinduced VO2 phase transition is fast and convenient, which is beneficial for studying the phase transition dynamics process. The related device applications include optical storage, all optical switches, photodetectors, phototransistors, etc;
3.The electric field induced VO2 phase change device has a simple structure and broad application prospects. It can be used as electrical switch, field effect transistor, electronic oscillator, memristor, RF switch, electro-optic modulator, etc;
4.The VO2 phase transition caused by ion doping and electrostatic effects under electrochemical conditions can be used in ionic liquid field-effect transistors and electrochromic devices;
5.The stress will change the VO2 lattice constant in, thus changing its electronic structure to cause phase transition, and can be used as a flexible stress sensor;
6.The magnetic susceptibility of VO2 will also change abruptly in the phase transition process, which makes it potentially valuable in the field of magnetic refrigeration and spintronic devices.
