Ames Laboratory physicists find strong bonds between rare-earth metals and graphene

Transistors and information storage devices are getting smaller and smaller. But, to go as small as the nanoscale, scientists must understand how just a few atoms of metals behave when deposited on a surface. 

Physicists at the U.S. Department of Energy's Ames Laboratory are studying the interaction of materials that are promising for use in nanoscale electronics: graphene and different types of metals. The team has discovered the rare-earth metals dysprosium and gadolinium react strongly with graphene, while lead does not.
