- Abstract
- We demonstrate that the Mott metal-Insulator transition (MIT) In single crystalline VO2 nanowires Is strongly mediated by surface stress as a consequence of the high surface area to volume ratio of Individual nanowires. Further, we show that the stress-induced antiferromagnetic Mott Insulating phase Is critical in controlling the spatial extent and distribution of the Insulating monoclinic and metallic rutile phases as well as the electrical characteristics of the Mott transition. This affords an understanding of the relationship between the structural phase transition and the Mott MIT.
