Excited state dynamics and semiconductor-to-metallic phase transition of VO2 thin film

Thermochromic CeO2–VO2 bilayers: Role of ceria coating in optical switching properties

“…The transition was described as a being a Mott-Hubbard transition [6]. Optical properties in the infrared range were extensively studied [7][8][9][10][11][12].…”

Eu-emission quenching by electron screening in VO2 thin films

“…Both of them were placed on a disk, and used as the target. The details of PLD processing has been given elsewhere [9,10]. A series of samples with film thickness measured from tens of nanometer up to 1.5 mm were prepared.…”

Charge transfer model of metal–insulator phase transition and ultrafast optical response in VO2

“…It is well known that optical pumping of VO 2 in insulator phase could induce an ultrafast PT to metallic phase (see, for instance, [3][4][5][6][7]). Recently we have proposed the exciton controlled model [5,6] which could explain the main features of such an effect including detected by us [7,5,6] threshold like re-switching of the relaxation direction with optical pumping or temperature tending to MI PT region.…”

“…Vanadium oxide (VO 2 ) is well known model system [1,2] for investigations of the metal-insulator (MI) phase transition (PT) [3][4][5][6][7][8][9][10][11][12][13]. This PT taking place here at $340 K is of the first order and is accompanied by structural PT.…”
