Ultrafast Electron-Lattice Coupling Dynamics in VO2 and V2O3 Thin Films
Elsa Abreu, Stephanie N. Gilbert Corder, Sun Jin Yun +11
Ultrafast optical pump - optical probe and optical pump - terahertz probe spectroscopy were performed on vanadium dioxide (VO2) and vanadium sesquioxide (V2O3) thin films over a wi…
Phase transition in bulk single crystals and thin films of VO2 by nano-infrared spectroscopy and imaging
Mengkun Liu, Aaron J. Sternbach, Martin Wagner +21
We have systematically studied a variety of vanadium dioxide (VO2) crystalline forms, including bulk single crystals and oriented thin films, using infrared (IR) near-field spectro…
Metal-insulator transition induced in SrTi_{1-x}V_xO_3 thin films
Man Gu, Stuart A. Wolf, Jiwei Lu
Epitaxial SrTi1-xVxO3 thin films with thicknesses of ~16 nm were grown on (001)-oriented LSAT substrates using the pulsed electron-beam deposition technique. The transport study re…
Dimensional-Crossover-Driven Mott Insulators in SrVO3 Ultrathin Films
Man Gu, Stuart A. Wolf, Jiwei Lu
High-quality epitaxial SrVO3 (SVO) thin films of various thicknesses were grown on (001)-oriented LSAT substrates by pulsed electron-beam deposition technique. Thick SVO films (~25…
Photoemission evidence for crossover from Peierls-like to Mott-like transition in highly strained VO
J. Laverock, A. R. H. Preston, D. Newby +8
We present a spectroscopic study that reveals that the metal-insulator transition of strained VO thin films may be driven towards a purely electronic transition, which does not…
VO2 nanosheets: controlling the THz properties through strain engineering
Elsa Abreu, Mengkun Liu, Jiwei Lu +5
We investigate far-infrared properties of strain engineered vanadium dioxide nanosheets through epitaxial growth on a (100)R TiO2 substrate. The nanosheets exhibit large uniaxial s…
