(Phys.org)—Illustrating the unusual way things work on the nanoscale, scientists have designed a new nanoelectromechanical system (NEMS) that produces mechanical motion due to the interactions between electrons—yet unlike ...
Scientists have, for the first time, identified a method of visualising the quantum behaviour of electrons on a surface. The findings present a promising step forward towards being able to manipulate and control the behaviour ...
