Findings could have applications in high-speed communications fields. Graphene has caused a lot of excitement among scientists since the extremely strong and thin carbon material was discovered in 2004. Just one atom thick, the honeycomb-shaped material has several remarkable properties combining mechanical toughness with superior electrical and thermal conductivity. Now a group of scientists at Iowa State University and the Department of Energy's Ames Laboratory, led by physicist...

Physicists study single-atom lasers Rainer Blatt's and Piet Schmidt's research team from the University of Innsbruck have successfully realized a single-atom laser, which shows the properties of a classical laser as well as quantum mechanical properties of the atom-photon interaction. The scientists have published their findings in the journal Nature Physics. The first laser was developed 50 years ago. Today we cannot imagine life without the artificially produced light waves - lasers have...

ETH Zurich researchers have successfully created an optical transistor from a single molecule. This has brought them one step closer to an optical computer.Internet connections and computers need to be ever faster and more powerful nowadays. However, conventional central processing units (CPUs) limit the performance of computers, for example because they produce an enormous amount of heat. The millions of transistors that switch and amplify the electronic signals in the CPUs are responsible...
