Abstract

In order to study the optical switching of vanadium dioxide (VO ₂) and its thermal hysteresis behavior, we fabricated VO ₂ films on glass substrates at various oxygen pressures. Only the VO ₂ films made at 5-10 mTorr displayed x-ray diffraction peaks and metal-insulator transition. Upon heating and cooling, remarkably, these samples exhibited significant optical switching behaviors with a clockwise thermal hysteresis in the infrared range of >850 nm or with a counterclockwise thermal hysteresis in the near visible range of 650-850 nm. The temperature dependence of optical absorption was explained by the O _2p-V _3d splitting depending on the structural transition of VO ₂.
