Researchers at the University of Gottingen have found a way to bind hydrogen atoms to graphene. Graphene cannot be used as a semiconductor, because it doesn’t have a bandgap.  By sticking hydrogen atoms to graphene  a bandgap can be formed. The researchers  bombarded graphene with hydrogen atoms. “The hydrogen atoms behaved quite differently than we ...
