Abstract
Embodiments of the disclosed technology include patterning a graphene sheet for biosensor and electronic applications using lithographic patterning techniques. More specifically, the present disclosure is directed towards the method of patterning a graphene sheet with a hard mask metal layer. The hard mask metal layer may include an inert metal, which may protect the graphene sheet from being contaminated or damaged during the patterning process.
