CFP highlighted twice by IOP!

Is there a tunable gap semiconductor? With graphene it's possible! An international team of physicists, with two CFP members, have shown that bilayer graphene has an electronic gap that can be tuned controllably between zero and mid-infrared energies The discovery was recently highlighted in physicsworld.com, the electronic bulletin of the Institute of Physics (IOP). The work by another CFP member has also been highlighted by IOP. Click below for more details.

Semiconductors are the key to standard logical device applications owing to their finite electronic gap. This gap, however, can only be changed slightly by external factors such as temperature or high pressure. An international team of physicists, composed of CFP members E. Castro and J. Lopes dos Santos (Portugal), N. Peres from Minho University (Portugal), K. Novoselov, S. Morozov, and A. Geim from Manchester University (UK), J. Nilsson and A. Castro Neto from Boston University (USA), and F. Guinea from CSIC (Spain), have shown that bilayer graphene hasan electronic gap that can be tuned controllably between zero and mid-infrared energies [Phys. Rev. Lett. 99, 216802]. This makes the bilayer graphene the only known semiconductor with tunable energy gap and may open the way for developing photo-detectors and lasers tunable by the electric field effect. The discovery was recently highlighted in physicsworld.com [if you don't have acess to IOP click here]. Previously the work on macroscopic entanglement by the CFP member Aires Ferreira had also been highlighted by IOP.
