Trapping electrons in a flat plane prevents them from moving freely in the third dimension and opens the door to a whole range of unusual physics. These effects are harnessed, for example, in modern ultrafast transistors, ...
(Â鶹ÒùÔºOrg.com) -- Berkeley Lab researchers have carried out the first experimental demonstration of GRIN plasmonics, a hybrid technology that opens the door to a wide range of exotic applications in optics, including superfast ...
(Â鶹ÒùÔºOrg.com) -- Using one of the most powerful magnets in the world, a small group of researchers has successfully isolated signs of electrical current flowing along the surface of a topological insulator, an exotic material ...
In the first decades of the 20th century, physicists hotly debated how to make sense of the strange phenomena of quantum mechanics, such as the tendency of subatomic particles to behave like both particles and waves. One ...
(Â鶹ÒùÔºOrg.com) -- In last week’s announcement of the Nobel Prize in Â鶹ÒùÔºics, the Royal Swedish Academy of Sciences lauded graphene’s "exceptional properties that originate from the remarkable world of quantum physics." ...
(Â鶹ÒùÔºOrg.com) -- Computers, light bulbs, and even people generate heat—energy that ends up being wasted. With a thermoelectric device, which converts heat to electricity and vice versa, you can harness that otherwise wasted ...
Researchers have taken one more step toward understanding the unique and often unexpected properties of graphene, a two-dimensional carbon material that has attracted interest because of its potential applications in future ...
Regarded as a possible replacement for silicon-based semiconductors, graphene, a sheet of pure carbon, has been discovered to have an uncommon and astonishing property that might make it better matched for future electronic ...
(Â鶹ÒùÔºOrg.com) -- Berkeley researchers have combined the scientific fields of transformation optics and plasmonics to demonstrate that with only moderate modifications of the dielectric component of a metamaterial, the physical ...
(Â鶹ÒùÔºOrg.com) -- With controlled stretching of molecules, Cornell researchers have demonstrated that single-molecule devices can serve as powerful new tools for fundamental science experiments. Their work has resulted in ...
