Graphene Electronics Moves Into a Third Dimension
February 2, 2012 — Wonder material graphene has been touted as the next silicon, with one major problem -- it is too conductive to be used in computer chips. Now scientists have given its prospects a new lifeline. ... > full story -
Data Storage: Magnetic Memories
February 1, 2012 — Magnetic random-access memory based on new spin transfer technology achieves higher storage density by packing multiple bits of data into each memory ... > full story -
Bilayer Graphene Works as an Insulator: Research Has Potential Applications in Digital and Infrared Technologies
January 24, 2012 — Physicists have identified a property of "bilayer graphene" that the researchers say is analogous to finding the Higgs boson in particle physics. The physicists found that when the number of ... > full story -
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 -
Ten-Second Dance of Electrons Is Step Toward Exotic New Computers
January 17, 2012 — Scientists have achieved a 100-fold increase in the ability to maintain control the spins of electrons in a solid material, a key step in the development of ultrafast quantum ... > 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
