Title
Self-patterned nanocircuits on VO2
Technique
Optical microscopy
Description
Crack patterning across the entire surface of an epitaxial VO2 thin film grown on TiO2(001). Metallic VO2 domains are framed by the insulating VO2 regions that cracks induce around them. The view looks like nanocircuits.
