Optical investigations on electronic structure changes related to the metal-insulator transition in VO2 film

C. H. Koo, J. S. Lee, M. W. Kim +4

We investigated optical absorption coefficient spectra of an epitaxial VO2 film in wide photon energy (0.5 - 5.0 eV) and temperature (100 - 380 K) regions. In its insulating phase,…
