Abstract

Non-degenerate pump (1.5 eV)-probe (0.4 eV) transmission spectroscopy on vanadium dioxide films grown on glass and three different sapphire substrates shows systematic variations with substrate that correlate with VO₂ grain size and laser fluence. Temperature dependent measurements showed changes in the electronic response that is proportional to the metallic fraction.
