Graphene's varying conductivity levels pinpointed

  • PDF
TechAndComputer (May 3, 2011) — Graphene is often touted as the latest "wonder material," and may be the electronics industry's next great hope for the creation of extremely fast electronic devices. Researchers at North Carolina State University have found one of the first roadblocks to utilizing graphene by proving that its conductivity decreases significantly when more than one layer is present.

Graphene's structure is what makes it promising...

New spin on graphene makes it magnetic

  • PDF
TechAndComputer (Apr. 15, 2011) — A team led by Professor Andre Geim, a recipient of the 2010 Nobel Prize for graphene, can now show that electric current -- a flow of electrons -- can magnetise graphene.

The results, reported in Science, could be a potentially huge breakthrough in the field of spintronics.

Spintronics is a group of emerging technologies that exploit the intrinsic spin of the electron, in addition to its fundamental electric...

Researchers advance toward hybrid spintronic computer chips

  • PDF
TechAndComputer (Apr. 27, 2011) — Researchers here have created the first electronic circuit to merge traditional inorganic semiconductors with organic "spintronics" -- devices that utilize the spin of electrons to read, write and manipulate data.

Ezekiel Johnston-Halperin, assistant professor of physics, and his team combined an inorganic semiconductor with a unique plastic material that is under development in colleague Arthur J. Epstein's lab...

Quantum mapmakers complete first voyage through spin liquid

  • PDF
TechAndComputer (Apr. 8, 2011) — Scientists from Oxford University have mapped a state of matter called 'quantum spin liquid', whose existence was proposed in the 1970s but which has only been observed recently.

Until now there has been very limited information describing the physical characteristics of a quantum spin liquid state, but researchers from Oxford University's Department of Physics working with the Rutherford Appleton Laboratory have...
