Thermoelectrics: From heat to electricity

A lot of heat gets lost during the conversion of energy. Estimates even put it at more than 70%. However, in thermoelectric materials, such as those being studied at the Institute of Solid State Physics at TU Wien, heat can ...

Close look at iron-based superconductor advances theory

(Phys.org)—Cornell researchers have resolved a longstanding theoretical debate about the electronic structure of iron-based superconductors by directly observing it at the atomic scale. The work is reported in the Feb. ...

Individual impurity atoms detectable in graphene

A team including physicists from the University of Basel has succeeded in using atomic force microscopy to obtain clear images of individual impurity atoms in graphene ribbons. Thanks to the forces measured in the graphene's ...

Researchers put a new spin on atomic musical chairs

Researchers from the National Institute of Standards and Technology and the Naval Research Laboratory have developed a new way to introduce magnetic impurities in a semiconductor crystal by prodding it with a scanning tunneling ...
