(Â鶹ÒùÔº) —A team of researchers with members from Italy and the U.S. has succeeded in building a transistor based on silicene, for the very first time. In their paper published in the journal Nature Nanotechnology, the ...
Some physical principles have been considered immutable since the time of Isaac Newton: Light always travels in straight lines. No physical object can change its speed unless some outside force acts on it.
The discovery of "topologically protected" electrical conductivity on the surface of some materials whose bulk interior acts as an insulator was among the most sensational advances in the last decade of condensed matter physics—with ...
The Hall effect, discovered in 1879, is observable when a Hall voltage perpendicular to the current is produced across a conductor under a magnetic field. Although the Hall effect was discovered in a sheet of gold leaf by ...
An odd, iridescent material that's puzzled physicists for decades turns out to be an exotic state of matter that could open a new path to quantum computers and other next-generation electronics.
The unusual properties of electrons responsible for the exotic conduction states on the surface of a class of materials known as topological insulators have been imaged by RIKEN researchers. The imaging technique promises ...
The prospect of transporting spin information over long distances in graphene, possible because of its small intrinsic spin–orbit coupling and vanishing hyperfine interaction, has stimulated intense research exploring spintronics ...
Â鶹ÒùÔºicists have, for the first time, explored in detail the time evolution of the conductivity, as well as other quantum-level electron transport characteristics, of a graphene device subjected to periodic ultra-short pulses. ...
(Â鶹ÒùÔº) —As computer chips continue to get smaller and more powerful, the field of electronics is approaching some severe limits.
Scientists believe they have found a way to explain why there are not as many galaxies orbiting the Milky Way as expected.
