New Breed of Electron Interactions in Quantum Systems
January 23, 2012 — Physicists have observed a new kind of interaction that can arise between electrons in a single-atom silicon transistor, offering a more complete understanding of the mechanisms that govern electron ... > full story -
Cooling Semiconductors by Laser Light
January 22, 2012 — Researchers have combined two fields -- quantum physics and nano physics -- and this has led to the discovery of a new method for laser cooling semiconductor membranes. Semiconductors are vital ... > full story -
Bucky Balls for Next-Generation Spintronics Devices
January 20, 2012 — The beauty of an electron’s spin is that it responds very rapidly to small magnetic fields. Such external magnetic fields can be used to reverse the direction of spin. In this way, information ... > full story -
Quantum Uncertainty: Are You Certain, Mr. Heisenberg?
January 16, 2012 — Heisenberg's Uncertainty principle is arguably one of the most famous foundations of quantum physics. It says that not all properties of a quantum particle can be measured with unlimited accuracy. ... > full story -
Theory Explains How New Material Could Improve Electronic Shelf Life
January 9, 2012 — Engineers have discovered that the new material graphene conducts heat about 20 times faster than silicon, making it an option as a semiconductor material that could produce quieter and ... > full story -
Graphene Reveals Its Magnetic Personality
January 8, 2012 — Can organic matter behave like a fridge magnet? Scientists have now shown that it can. Researchers took nonmagnetic graphene and then either 'peppered' it with other nonmagnetic atoms like fluorine ... > full story -
'Nanowiggles:' Scientists Discover Graphene Nanomaterials With Tunable Functionality in Electronics
January 4, 2012 — Scientists have used supercomputers to uncover the properties of a promising form of graphene, known as graphene nanowiggles. What they found was that graphitic nanoribbons can be segmented into ... > full story -
Emerging New Properties at Oxide Interfaces
November 25, 2011 — Researchers discovered a collective electronic state not seen before in the bulk of either two individual insulating oxides, thus demonstrating that electrons at their interface can now exhibit ... > full story -
Unearthing a New Quantum State of Matter: Quantum Physics Discoveries Could Change Face of Technology
November 21, 2011 — Researchers have made advances in better understanding correlated quantum matter that could change technology as we know it, according to a new ... > full story -
Secrets of Tunneling Through Energy Barriers: How Massless Electrons Tunnel Through Energy Barriers in a Carbon Sheet Called Graphene
November 7, 2011 — Electrons moving in graphene behave in an unusual way, as demonstrated by 2010 Nobel Prize laureates for physics Andre Geim and Konstantin Novoselov, who performed transport experiments on this ... > full story -
Europe's Top Microscope for Creating Tomorrow's Materials
October 28, 2011 — Europe's most precise electron microscope is now in use in Sweden. The 80-300 transmission electron microscope has been adjusted so it now provides a resolution of less than 0.7 Å (about half ... > full story -
Data Transmission for the Internet of Tomorrow: Scientists Develop New Concept for Ultrafast Lasers
October 28, 2011 — Electrical engineers in Germany have succeeded in developing a new concept for ultrafast semiconductor lasers. The researchers make clever use of the intrinsic angular momentum of electrons, called ... > full story
