Electron travel 100 times faster in graphene
Tuesday, March 25th, 2008 | Nanotechnology
Science daily has got another research article which shoes that electrons travel 100 times faster in graphene than in silicon. Graphene is currently the only semi-conductor element which has so much electron mobility at room temperature. So this opens doors to graphene replacing silicon chips. I have already written about this in my earlier post. Graphene is not much new than graphite, the one in your pencil. The carbon atoms in graphite are in single sheet type. Also graphene has 35 % less resistivity than copper metal at room temperature. Silicon as i said earlier is limited (the special grade needed) and we are developing PC’s at fast pace and we need something that can replace silicon chips in computers and other devices using semi-conductors. Also graphene doesn’t heat as much as silicon, rather to say that it cools faster than silicon which heats up much
