The electrical conductance at different locations on individual atoms has been measured by scientists in Japan. The experiment involved adding and removing electrons from atoms on a surface by using a ...

Quantized conductance — whereby the current through a wire changes in a stepwise, rather than continuous manner — has been seen in very narrow ribbons of graphene for the first time. The discovery was ...

Scientists from the University of Pittsburgh have discovered a new specialized phase of matter. By electrifying an interface made of lanthanum aluminate and strontium titanate, the researchers ...
