Coexistent VO₂ (M) and VO₂ (B) Polymorphous Thin Films with Multiphase-Driven Insulator-Metal Transition.

ABSTRACT: Reversible insulator-metal transition (IMT) and structure phase change in vanadium dioxide (VO₂) remain vital and challenging with complex polymorphs. It is always essential to understand the polymorphs that coexist in desired VO₂ materials and their IMT behaviors. Different electrical properties and lattice alignments in VO₂ (M) and VO₂ (B) phases have enabled the creation of versatile functional devices. Here, we present polymorphous VO₂ thin films with coexistent VO₂ (M) and VO₂ (B) phases and phase-dependent IMT behaviors. The presence of VO₂ (B) phases may induce lattice distortions in VO₂ (M). The plane spacing of (011)_M in the VO₂ (M) phase becomes widened, and th
