Study images hot-electron Thomson cooling beyond Boltzmann-Onsager framework
Original: Imaging hot-electron Thomson cooling beyond the Boltzmann–Onsager framework
Researchers report direct imaging of hot-electron Thomson cooling in a system that operates beyond the conventional Boltzmann-Onsager framework, which has long governed the linear description of thermoelectric effects. The work shows cooling driven by nonlinear thermoelectric transport in hot electrons, extending how heat and charge interplay can be understood and imaged at small scales.
Why now: The finding challenges a foundational framework in thermoelectric theory and demonstrates a new experimental imaging capability, drawing attention in the physics community.
