Stretchable graphene transistors overcome limitations of other materials
A first: Stanford engineers build computer using carbon nanotube technology
A team of Stanford engineers has built a basic computer using carbon nanotubes, a semiconductor material that has the potential to launch a new generation of electronic devices that run faster, while using ...
Electrons are not enough: Cuprate superconductors defy convention
(Phys.org) —To engineers, it's a tale as old as time: Electrical current is carried through materials by flowing electrons. But physicists at the University of Illinois and the University of Pennsylvania ...
Scientists build thinnest-possible LEDs to be stronger, more energy efficient
(Phys.org) —Most modern electronics, from flat-screen TVs and smartphones to wearable technologies and computer monitors, use tiny light-emitting diodes, or LEDs. These LEDs are based off of semiconductors ...
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.
Gold nanorods provide whole new way of harvesting energy from the sun
A new method of harvesting the Sun's energy is emerging, thanks to scientists at UC Santa Barbara's Departments of Chemistry, Chemical Engineering, and Materials. Though still in its infancy, the research promises to convert ...
Nanoengineers develop basis for electronics that stretch at the molecular level
Nanoengineers at the University of California, San Diego are asking what might be possible if semiconductor materials were flexible and stretchable without sacrificing electronic function?
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 ...
