Abstract

Electrically written silver oxide nanoscale break junctions clearly show asymmetric, wavelength-dependent photoconductivity, but only when either the anode oxide or the silver nanoclusters spanning the junction are illuminated. The higher oxygen content in the cathode increases the cathode oxide band gap and inhibits production of photoinjecting Ag nanoclusters. The optical and electronic properties of silver and its oxides suggest that useful nanoscale optoelectronic components can be created through a very simple one-step electromigration process.
