Self-assembled monolayers create p-n junctions in graphene films
11 December, 2012 by John ToonA low-temperature, controllable and stable method has been developed to dope graphene films using self-assembled monolayers (SAM) that modify the interface of graphene and its support substrate. Using this concept, a team of researchers at the Georgia Institute of Technology has created graphene p-n junctions - which are essential to fabricating devices - without damaging the material’s lattice structure or significantly reducing electron/hole mobility.

Surprising findings could influence material choices in nanoelectronics
12 November, 2012To build the computer chips of the future, designers will need to understand how an electrical charge behaves when it is confined to metal wires only a few atom-widths in diameter. A team of physicists has shown that electrical current may be drastically reduced when wires from two dissimilar metals meet.
Reducing robot energy consumption
31 October, 2012Robots could reduce their power consumption by as much as 10-fold by ‘stutter jumping’ - taking a short hop before a big jump.
