The model of the nanothermoelectric engine with a spin-degenerate level quantum dot. Heat flux from the hot reservoir at temperature gets into the quantum dot and power is delivered and heat flux dissipates to the cold reservoir at temperature .
The dimensionless power output and the efficiency versus the energy-level of the quantum dot, for the parameters , , , , , , , , and .
The optimal dimensionless power output , the corresponding efficiency , and the Carnot efficiency versus the temperature ratio of two heat reservoirs, for the parameters , , , , and .
The curves of a nanothermoelectric engine. The values of the relevant parameters are the same as those used in Fig. 3.
Plot of vs , for the parameters , , , and .
