Electrical and Photoelectrical Properties of Reduced Graphene OxideâPorous Silicon Nanostructures
Abstract In this work, the hybrid structures were created by electrochemical etching of silicon wafer and deposition of reduced graphene oxide (RGO) on the porous silicon (PS) layer. With the help of SEM and AFM, the formation of hybrid PSâRGO structure was confirmed. By means of currentâvoltage characteristic analysis and impedance spectroscopy, we studied electrical characteristics of PSâRGO structures. The formation of photosensitive electrical barriers in hybrid structures was revealed. Temporal parameters and spectral characteristics of photoresponse in the 400â1100-nm wavelength range were investigated. The widening of spectral range of photosensitivity of the hybrid structures in short-wavelength range in comparison with single-crystal silicon was revealed. The obtained results broaden the prospects of application of the PSâRGO structures in photoelectronics
