Tuning the optical properties of p-CuO films by Graphene incorporation for superior p-CuO/n-Si heterojunction photo-detector performance

The present work focuses on the influence of graphene nano-particles on the optical, electrical and photo-catalytic activity of p-CuO/n-Si heterojunction. Both the CuO and graphene nano-particle incorporated CuO (G-CuO) films are grown by Chemical Bath Deposition (CBD) method. A comparative study has been performed on the systematic change of the film morphology and optoelectronic property of the grown films. The study suggests that the electronic and photo-detecting properties of the CBD grown CuO films can be improved by incorporating graphene in it.
