A graphene cantilever beam of arbitrary shape by patterning suspended graphene using a focused ion beam (FIB) is fabricated. Suspended graphene was formed by transferring graphene over a trench structure and patterned the suspended graphene into a cantilever beam structure. When the suspended graphene is patterned by an FIB, the high-ion irradiation of FIB deforms the shape of the cantilever beam;...
A standard exfoliation process of graphene involves several problems associated with damage of graphene and long-time consumption. Here we demonstrate a direct physical exfoliation and transfer processes of graphene grown via ethanol-chemical vapor deposition (CVD). Our exfoliation process exploits a polydimethylsiloxane (PDMS) stamp for conformal contact with graphene. Moreover, it rapidly exfoliates...
