Optical properties of VO${}_2$ films at the phase transition: influence of substrate and electronic correlations

Tobias Peterseim, Martin Dressel, Marc Dietrich +1

Thin films of VO${}_2$ on different substrates, Al${}_2$O${}_3$ and SiO${}_2$/Si, have been prepared and characterized from room temperature up to 360 K. From the band structure in the rut…
