Cooling graphene with electrons

Description

Transistors are shrinking, but the heat they produce is becoming a problem. One solution could be to cool them with electrons, relying on what is known as the Peltier effect. This works for beer, and Ivan Vera Marun, a physicist at the Universities of Groningen and Manchester, has now shown that it also works on two-dimensional graphene sheets. The work was published in Nature Communications on 10 May.
