Five-year grants totalling £20m will be given to Bath, Imperial, London School of Economics, Edinburgh, Exeter, Heriot-Watt, Lancaster, Manchester and Strathclyde Universities as a result of the EPSRC 2008 Science ...
HRL Laboratories, LLC, demonstrated the first graphene field-effect transistors (FETs) using epitaxial graphene film operating in the radio frequency (RF) range. Prior efforts with graphene FETs used exfoliated graphene films. The HRL milestone is a key step toward wafer-scale high-speed RF FETs, which could lead to a new generation of carbon-based RF integrated circuits for ultra-high-speed, ultra-low-power applications.
If you look carefully at a football, you will notice that its surface is composed of hexagons and pentagons. Hexagons lie side by side while any pentagon is surrounded by five hexagons. How many corners and edges are there? Football players do not have to know that as long as they do pass and shots right; an architect or structural physicist, however, could readily give the answer.
A team at Rice University has determined that a strip of graphite only 10 atoms thick can serve as the basic element in a new type of memory, making massive amounts of storage available for computers, handheld media play...
Graphene is a perfect example of the wonders of nanotechnology, in which common substances are scaled down to an atomic level to uncover new and exciting possibilities.
Graphene is created when graphite — the m...
Andre Geim developed the first two-dimensional crystals made of carbon atoms. These graphenes not only promise to revolutionize semiconductor, sensor, and display technology, but also lead us to expect breakthroughs in basic research in quantum physics.
The Instituto Madrileño de Estudios Avanzados en Nanociencia (IMDEA Nanoscience) collaborates together with the University of Hamburg in the development of composite materials based on semiconductor nanoparticles an...
Recently, SUN Qingfeng with the Lab for Condensed Matter Theory and Materials Computation, CAS Institute of Physics made an intensive study on the electron transport through graphene p-n junctions in cooperation with LON...
Graphene is the latest nanoscale form of carbon to be discovered and it is currently the hottest topic in condensed matter physics and materials science due to its novel electronic properties. An important feature of graphene, which has not been exploited so far, has been its edges, where interesting electrocatalytic properties and sites for functionalization can develop.
Graphene is a two-dimensional material that consists of a hexagonal array of carbon just one atom thick . Although it is essentially just a single sheet of graphite, its properties are remarkable and unique. Notably, its charge carriers behave like massless relativistic particles, and move at a speed of just 300 times less than the speed of light-many times more quickly than in silicon.
