New Graphene-Info site launched

We're happy to announce a new addition to the Metalgrass site network: Graphene-Info. Graphene is a sheet, one-atom-thick of carbon atom, in a honeycomb crystal lattice. If you use many layers of graphene, stacked one on top of the other, you’ll get Graphite. Graphene has many uses - Spintronics, sensors, ICs (for example a transparent backplane for OLEDs), ultra-capacitors and more.

We hope you'll enjoy the new site...

UK research team gets 700,000$ grant to study silicon structures for spintronics

UK researchers (from the University of Surrey and two more institutes) have been awared a 430,000GBP (around 700K$), 3-year grant to develop silicon structures for spintronic semiconductors. This is funded by the UK Engineering and Physical Sciences Research Council and the National Science Foundation of China

The project could lead to cheaper and more sophisticated computer processing technologies.While silicon has not been the material of choice for spintronic research, the team says exploration of silicon based platforms is important due to the potential for exploiting an extremely pure material and the far cheaper and more sophisticated processing technologies available.
The project will focus on manipulating electron spins with laser beams will look to build a prototype device.

American Elements to expand its bismuth telluride (Bi2Te3) production facilities

American Elements announced the further expansion of its bismuth telluride (Bi2Te3) production facilities to meet growing demand for the semiconductor material in computer chip production. BiTe forms available include powder, pieces (also lump and chunk), plates, discs, and sputtering targets for thin film deposition.

Bismuth Telluride may increase the speed of microchips, and be the basis of spintronics. 

At full capacity, the new facility can deliver several metric tons monthly.
