Melding of two-dimensional (2D) materials with conventional three-dimensional (3D) materials is leading to new, versatile, and robust photodetector devices. We have developed devices utilizing reduced graphene-oxide on gallium nitride material and graphitic carbon-nitride on silicon. The devices demonstrate significant enhancement in the performance in terms of their figure-of-merits parameters as compared to the respective parent platforms. The main aim of this talk is to propose a new generation of low-cost, high performance photodetectors with enhanced device performance as compared to current prevalent technologies.
