Controlling the formation of graphene nano-scrolls

Can graphene - a newly discovered form of pure carbon that may one day replace the silicon in computers, televisions, mobile phones and other common electronic devices - be made to bend, twist and roll? Physicists at UC San Diego and Boston University think so.

Junctionless transistor outperforms nanowire MOSFET

Recent modeling results obtained in imec for a GaAs and Si nanowire indicate that the nanowire pinch-off FET can outperform the nanowire MOSFET. These results combined with scalability and ease of processing make the junctionless transistor a true competitor for the nanowire MOSFET.

A little less force: Making Atomic Force Microscopy work for cells

Researchers have developed nano-sized cantilevers whose gentle touch could help discern the workings of living cells and other soft materials in their natural, liquid environment. Used in combination with a revolutionary detection mechanism, this new imaging tool is sensitive enough to investigate soft materials without the limitations present in other cantilevers. By placing a nanowire cantilever in the focus of a laser beam and detecting the resulting light pattern, scientists at the Molecular Foundry believe atomic force microscopy can be used to non-destructively image the surface of a biological cell.
