Effect of adhesives on characteristics of CVD graphene

Abstract

Characteristics of graphene when transferred using various adhesives have been investigated. The primary objective was to identify an adhesive capable of withstanding elevated temperatures common in photolithography (100-150°C) without compromising graphene properties. The project consisted of three parts. First, the graphene growth by chemical vapor deposition (CVD) was optimized by adjusting gas flow rates during the process and input parameters such as time and temperature. The quality of the graphene was examined at different regions of the copper foil used as a catalyst in CVD. Second, the impact of different adhesives on graphene doping and charge-carrier mobility was explored. Finally, the role of multilayer patches in graphene’s interaction with adhesives was discovered by applying different adhesives to both sides of the graphene.
