Rutgers University researchers have shown graphene is twice as good at active cooling as other materials , and is ideal for use in transistors , reports a study published in Proceedings of the National Academy of Sciences . The team placed a one - atom - thick layer of graphene , which is 100 times stronger than steel and quickly diffuses heat , on a substrate made of boron oxide . Apart from any fair dealing for the purpose of private study or research, no part may be reproduced without the written permission. By applying an electrical current , they found that the graphene carried away the heat much more efficiently than passive cooling and other non - electric cooling methods . Another advantage is that no moving parts are required .
