Description:
Author(s): E. Thiébaut, C. Goupil, F. Pesty, Y. D’Angelo, G. Guegan, and P. Lecoeur The knife cuts both ways: Rather than turning waste heat into electricity as usual, a thermoelectric material instead can use electrical current to remove heat, if you prefer. Due to the robustness of the Peltier effect, solid-state cooling devices have great potential for application. Considering engineered materials of graded composition, the authors analytically establish a criterion that allows drastic improvement of cooling performance, compared to an everyday, homogeneous material. Numerical modeling further allows quantitative investigation of the rate and sources of entropy production associated with such a device. [Phys. Rev. Applied 8, 064003] Published Mon Dec 04, 2017
