Authors


Abstract

original image

A simple method to fabricate a visible light-detectable hybrid nanodevice based on TiO2 nanoparticles and pristine graphene, ideally combining the advantages of both, is demonstrated. High photosensitivity of the hybrid device under visible and UV light irradiation paves the way for its application as a broad wavelength photodetector.
