On-surface synthesis of graphene nanoribbons could advance quantum devices

DOE/Oak Ridge National Laboratory
Peer-Reviewed Publication

An international multi-institution team of scientists has synthesized graphene nanoribbons -- ultrathin strips of carbon atoms -- on a titanium dioxide surface using an atomically precise method that removes a barrier for custom-designed carbon nanostructures required for quantum information sciences.

Blocking vibrations that remove heat could boost efficiency of next-gen solar cells

DOE/Oak Ridge National Laboratory
Peer-Reviewed Publication

Led by the Department of Energy's Oak Ridge National Laboratory and the University of Tennessee, Knoxville, a study of a solar-energy material with a bright future revealed a way to slow phonons, the waves that transport heat. The discovery could improve novel hot-carrier solar cells, which convert sunlight to electricity more efficiently than conventional solar cells by harnessing photogenerated charge carriers before they lose energy to heat.
