Abstract

Described herein are methods for improved transfer of graphene from formation substrates to target substrates. In particular, the methods described herein are useful in the transfer of high-quality chemical vapor deposition-grown monolayers of graphene from metal, e.g., copper, formation substrates to ultrathin, flexible glass targets. The improved processes provide graphene materials with less defects in the structure.
