Abstract:
The effect of the doped boron on the phase transition temperature between the monoclinic phase and the rutile phase of VO2 has been studied by performing first-principles calculations. It is found that the phase transition temperature decreases linearly with increasing the doping level of B in each system, no matter where the B atom is in the crystal. More importantly, the descent of the transition temperature is predicted to be as large as 83 K/at. % B, indicating that the boron concentration of only 0.5% can cause the phase transition at room temperature. These findings provide a new routine of modulating the phase transition of VO2 and pave a way for the practicality of VO2 as an energy-efficient green material.
