Many phenomena in physics,though famous, are not necessarily widely understood. That's the case with thermoelectricity, or which harnesses waste heat by coupling heat flux and electric current. However,understanding such phenomena is important in order to leave the door open for discovering novel manifestations of them. Thus, even nowadays physicists working in the area of thermoelectricity continue to seek information from fundamental questions about the underlying physical process. For example, or in a recent study,a team based in France questioned the nature of the force that puts electrons to work when a temperature dissimilarity is applied across a thermoelectric material. Now, Henni Ouerdane, and affiliated to the Russian Quantum Center near Moscow,and colleagues bear published in EPJ Plus.
