Laser Induced Strain Engineering of Graphene
Researchers at Purdue University have developed a technique to tailor the electronic properties of graphene using laser shock pressure to produce controlled straining. The graphene sheet is conformally pressed onto a patterned mold. It takes the shape of the pattern, resulting in tunable strains. It is a one-step operation, with the shock taking only tenths of a nanosecond. The laser shock approach is fast, tunable, low-cost, and can be scaled to produce rolls of graphene in a short period. It is a cost-effective means to produce large amounts of patterned graphene for use in nanoelectrical devices.
