Optical and Electrical Properties of Vanadium Pentoxide Films Deposited on Different Substrates

Influence of film thickness on structural and optical-switching properties of vanadium pentoxide films

“…4,5 Owing to their outstanding optical, electrical and thermal properties, V 2 O 5 thin films have been intensively exploited in many potential applications such as switching elements, smart windows, storage devices and terahertz modulators. [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20] Thin films of V 2 O 5 with fairly good electrochemical performances were recently prepared by different deposition techniques, including sol-gel process, spray pyrolysis, thermal evaporation, electron beam evaporation, pulsed laser deposition (PLD), chemical vapour deposition, ion beam sputtering, and D.C. or R.F. sputtering.…”

“…sputtering. [6][7][8][9][10] And more importantly, reactive magnetron sputtering can prepare large and uniform films more easily than PLD or laser ablation, and can prepare higher quality films than sol-gel method or thermal evaporation method. Hence, in this study, reactive magnetron sputtering was used to prepare V 2 O 5 films.…”

“…21 Recently, we have produced V 2 O 5 films on single-crystal diamond with very low transmission in the metal state and D T values of around 10 at a wavelength of 1064 nm. 6 In the earlier work, switching was induced by direct (non-optical) heating. 7 However, because the films are absorbent in the infra-red spectroscopy, they can be efficiently pumped with infra-red light.…”
