Abstract

In this letter, we demonstrated the photoexcitation of metallic phase vanadium dioxide (VO₂) with time-resolved x-ray diffraction measurements. Through the photoexcitation, the metallic phase VO₂ transitioned to the similar transient state, which was presented in the insulator to metal phase transition in the time-scale of ∼10 ps. This transient state was accessed only by the photoexcitation and not through further thermal excitation. The presence of the transient state could be an important factor in any further application of the phase transition phenomena.
