Light on twenty-year-old electron mystery

Groningen scientists have found an explanation for a mystery that has been puzzling the physics community since 1995. In the scientific journal Nature on Thursday 28 August (Advance Online Publication), they explain why electrons pass through very tiny wires (known as quantum point contacts) less smoothly than expected. The observations of the group led by Prof. C.H. van der Wal of the Zernike Institute for Advanced Materials of the University of Groningen will affect electronics on a nanoscale: "Our thinking about this has been too naïve so far."
