Stories about: Hall Effect

Fractional Quantum Hall Effect Demonstrated in Graphene Graphene, the one-atom-thick sheet of carbon atoms that was discovered in 2004 at the University of Manchester, is the most avidly researched material today in the field of condensed-matter physics. Because electrons flow in a very peculiar way through it, experts believe it may constitute the replacement of choice f... 15 October 2009 04:55 GMT Researchers Discover new Quantum State of Matter Once it was thought that the quantum Hall effect is experienced in materials under the influence of external magnetic fields, albeit Princeton University researchers revealed that it may also be experienced in bulk bismuth-antimony crystal without any interference from magnetic fields. The discovery could possibly le... 25 April 2008 10:40 GMT
