According to the Wiedemann-Franz (WF) law, the electrical conductivity of a metal is linked to its thermal counterpart, provided that the heat carried by the phonons is negligible and the electrons do not suffer inelastic ...
Researchers at the University of North Carolina at Chapel Hill made a one-way street for electrons that may unlock the ability for devices to process ultra-high-speed wireless data and simultaneously harvest energy for power. ...
