Microscopic nature of the asymmetric hysteresis in the insulator-metal transition of VO${}_2$ revealed by spectroscopic ellipsometry

Ievgen Voloshenko, Florian Kuhl, Bruno Gompf +4

Systematic spectroscopic ellipsometry investigations have been performed in order to elucidate the asymmetric insulator-to-metal transition in thin VO${}_2$ films. The comprehensive…
