Effect of inhomogeneities and substrate on the dynamics of the metal-insulator transition in VO${}_2$ thin films

M. Rodriguez-Vega, M. T. Simons, E. Radue +6

We study the thermal relaxation dynamics of VO${}_2$ films after the ultrafast photo-induced metal-insulator transition for two VO${}_2$ film samples grown on Al${}_2$O${}_3$ and TiO${}_2$ s…
