Graphene: It is all about the toppings

Graphene consists of a single layer of carbon atoms.
Exceptional electronic, thermal, mechanical, and optical properties
have made graphene one of the most studied materials at the moment.
For many applications in electronics and energy technology,
however, graphene must be combined with other materials. Since
graphene is so thin, its properties drastically change when other
materials are brought into direct contact with it.
