Researchers combine copper and graphene for quicker, cheaper computer cooling
Author: Jade Kim
In electronics heat is often the enemy, but research at North Carolina State University may have resulted in a way to keep things cool in a less-expensive manner than is currently possible. Dr. Jag Kasichainula achieved the feat by using graphene. Compromised of honeycombed carbon atoms, graphene is being utilized for a number of different breakthroughs and experiments; in this case it is combined with copper to create a composite heat spreader. The spreader then connects to the electronic device in question with a indium-graphene film. The higher thermal conductivity of both materials allows the composite spreader to draw heat away approximately 25 percent faster than commonly-used copper versions. Copper is also notoriously expensive,…
