Electrical Transition in Isostructural VO2 Thin-Film Heterostructures
Scientific Reports, 9(1).
TL;DR:
This work designs a novel strain-stabilized isostructural VO2 epitaxial thin-film system where the electrical transition occurs without any observable structural transition, and calculates that the strain in monoclinic structure reduces the difference between long and short V-V bond-lengths in monOClinic structures which leads to a systematic decrease in the electronic bandgap of VO2.
