Formation of Graphene Island on Si (100) Substrate Prepared by Simple-Spray Method: Morphological and Optical Analyses

Abstract

We study morphology and optical properties of graphene. A graphene on Si (100) substrate has been successfully prepared by the simple-spray method. The heat treatment of 150°C was performed during the deposition to assist the distribution of graphene on Si (100) substrate. We revealed that the graphene was well distributed with an island structure was observed. The real part and imaginary part of the refractive index of the graphene island were presented. Furthermore, the optical analysis revealed that the UV absorption was observed in our system. The results shown here would provide a good understanding of the graphene island properties, which potential for the optoelectronic-based application. In any case, our proposed method would reduce the complexity of the production of graphene with the inexpensive and simple procedure.
