Interfacial nanosphere lithography toward Ag2S-Ag heterostructured nanobowl arrays with effective resistance switching and enhanced photoresponses.

Unique Ag2 S-Ag heterostructured nanobowl arrays consisting of Ag2 S nanonets lying on Ag nanobowl arrays are fabricated by two-step nanosphere lithography at the gas-liquid interface. These Ag2 S-Ag heterostructured nanobowl arrays exhibit effective resistance switching behaviors and enhanced photoresponses, showing potential application in both electric devices and photocatalysis.
