The two components of the crystallographic transition in VO2
TLDR
In this article, two distinguishable mechanisms of the monoclinic-to-tetragonal transition in VO 2 are identified: an antiferroelectric-toparaelectric transition at a temperature T t as well as a change from homopolar to metallic VV bonding at T t.About:

Masaki Nakano,Keisuke Shibuya,Daisuke Okuyama,Takafumi Hatano,Shimpei Ono,Masashi Kawasaki,Yoshihiro Iwasa,Y. Tokura +7 more
TL;DR: This work prepared metal–insulator–semiconductor field-effect transistors based on vanadium dioxide and found that electrostatic charging at a surface drives all the previously localized charge carriers in the bulk material into motion, leading to the emergence of a three-dimensional metallic ground state.

Evidence for a structurally-driven insulator-to-metal transition in VO 2 : A view from the ultrafast timescale
TL;DR: In this article, the authors apply ultrafast spectroscopy to establish a time-domain hierarchy between structural and electronic effects in a strongly correlated electron system, and they discuss the case of the model system, a prototypical nonmagnetic compound that exhibits cell doubling, charge localization, and a metal-insulator transition below 340 K.

Direct cation- -cation interactions in several oxides
TL;DR: In this paper, it was pointed out that interactions between octahedral-site cations are cation-anion-cation interactions if the cation occupied octahedra share a common corner, but may be primarily cation -cation (no anion intermediary) if they share either a common edge or a common face.
