High-purity Vanadium (V) metal sputtering targets for DC reactive magnetron sputtering of vanadium dioxide (VO₂) phase-change films, vanadium nitride (VN), and vanadium pentoxide (V₂O₅) electrochromic layers. VO₂ undergoes a sharp insulator-to-metal transition (IMT) at ~68°C with a 3–4 order-of-magnitude change in electrical resistivity and infrared transmittance — making it the premier material for smart windows, optical switching, and IR detectors.
