A new class of electron interactions in quantum systems
Date:1/23/2012

ysics," says Tettamanzi.

"In our case this crossover was observed simply by using a semiconductor device which is not too different from the transistor you use daily to send your emails."

Tettamanzi, who was recently awarded a prestigious ARC Discovery Early Career Researcher Award fellowship, will now investigate another transport mechanism that can arise in quantum dots and single atom transistors called "quantised charge pumping".

The idea here is to create a current flowing through a nanostructure without applying a voltage between the leads, but by applying varying potentials at one or more gates of the transistor, in an apparent violation of Ohm's law.
