Abstract: It has been shown that temperature changes in the newly discovered fine structure of the dielectric spectra of nanocrystalline vanadium dioxide films provide exclusive experimental evidence for the complex Mott-Peierls nature of the complex semiconductor-metal phase transition in VO$_2$ films.

Keywords: dielectric spectroscopy, vanadium dioxide, semiconductor-metal phase transition, VO$_2$ films, specific conductivity.
