Electrons 100 Times Faster in Graphene Graphene has a thermal conductivity fifty percent higher than that of carbon nanotube, and about 10 times higher than metals such as copper and aluminum. Better still, graphene combines both semiconductor and metal properties which make it ideal for a replacement for semiconductors currently used in computer chips. G... 24 March 2008 11:32 GMT Surprise, Superconductors! Superconductivity is a property of materials exhibited through zero electrical resistance while being cooled to temperatures close to absolute zero. However, aside the vast majority of materials that require such low temperatures, there is a series of special materials, mostly ceramics, which experience zero electric... 13 February 2008 03:41 GMT
