Abstract
We report photoinduced reentrant insulator-metal-insulator transitions in a low-dimensional nanoscale system of vanadium oxide nanotubes, a Mott insulator in the dark with no metal-insulator transitions. The nature of the spatially inhomogeneous intermediate metallic phase was elucidated by the photocurrent decay analysis of the system.
