 | Scientists at the University of California, Riverside, report the first direct observation and controlled creation via simple thermal manipulation of one- and two-dimensional ripples in graphene sheets. The result has important implications for controlling thermally induced stress in graphene electronics and represents the first step towards strain-based graphene engineering. The thermal contraction of graphene had been predicted theoretically, but the UC Riverside lab is the first to demonstrate and quantify the phenomenon experimentally. ...> Full Article |
