Going beyond Landauer scattering theory to describe spatially resolved nonlocal heating and cooling in quantum thermoelectrics
Nanoscale thermometry is starting to reveal answers to the 40 year old question of where dissipation (Joule heating) occurs when an electric current flows through a nanostructure. Since the 1980s, Landauer scattering theory has only said that it happens ``somewhere'' in the leads connected to that nanostructure. This theoretical work goes beyond this by modeling spatially resolved Joule heating and thermoelectric cooling. It predicts an unexpected nonlocality in heat transfer between electrons and phonons, with heating and cooling spots at a finite distance from the voltage drop that causes them.
