As in any other engineering activity, the design of semiconductor chips (ICs) encompasses several separate, but often closely coupled, design activities. Today's system-on-a-chip (SoC) development ...

A team of US researchers has unveiled a device that can conduct electricity along its fractionally charged edges without losing energy to heat. Described in Nature Physics, the work, led by Xiaodong ...

Researchers used magnetic imaging to obtain the first direct visualization of how electrons flow in a special type of insulator, and by doing so they discovered that the transport current moves ...
