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 关键词: electromigration;energy gap;nanocontacts;nanostructured materials;optoelectronic devices;photoconductivity;silver compounds;asymmetric photoconductivity;silver oxide nanoscale break junctions;wavelength-dependent photoconductivity;anode oxide;silver nanoclusters;oxygen content;cathode oxide band gap;photoinjecting Ag nanoclusters production;electronic properties;nanoscale optoelectronic components;one-step electromigration process;optical properties;AgO
