Abstract

Tailoring resistance response using periodic nanostructures is one of the key issues in the current research. Two-dimensional colloidal crystals (CCs) structure is one of popular periodic nanospheres' structures and most of reports are focused on anomalous transmission of light or biomedical applications. In this work, a light-induced resistance effect is observed on silicon-based Au films covered CCs, featuring a remarkable resistance change as much as 56% and resistance switching characteristic. The diffusion and recombination of photocarriers is the crucial factor for this effect. This finding will expand photoelectricity functionality and be useful for future development of CC-based photoelectric devices.
