Nanowires grown on graphene have surprising structure

(Phys.org) —When a team of University of Illinois engineers set out to grow nanowires of a compound semiconductor on top of a sheet of graphene, they did not expect to discover a new paradigm of epitaxy.

Scientists use DNA to assemble a transistor from graphene

(Phys.org) —Graphene is a sheet of carbon atoms arrayed in a honeycomb pattern, just a single atom thick. It could be a better semiconductor than silicon – if we could fashion it into ribbons 20 to 50 atoms wide. Could ...

Scientists make a quantum harmonic oscillator at room temperature

A quantum harmonic oscillator—a structure that can control the location and energy of quantum particles that could, in the future, be used to develop new technologies including OLEDs and miniature lasers—has been made ...
