Three-terminal semiconductor junction thermoelectric devices: improving performance
A three-terminal thermoelectric device based on a p–i–n semiconductor junction is proposed, where the intrinsic region is mounted onto what is typically a bosonic thermal terminal. Remarkably, the figure of merit of the device is governed also by the energy distribution of the bosons participating in the transport processes, in addition to the electronic. An enhanced figure of merit can be obta...
متن کاملThermoelectric efficiency at maximum power in a quantum dot
We identify the operational conditions for maximum power of a nanothermoelectric engine consisting of a single quantum level embedded between two leads at different temperatures and chemical potentials. The corresponding thermodynamic efficiency agrees with the CurzonAhlborn expression up to quadratic terms in the gradients, supporting the thesis of universality beyond linear response. Copyrigh...
متن کاملEfficiency of Inhomogeneous Thermoelectric Generators
We revisit the classical problem of the efficiency of inhomogeneous thermoelectric generators. The effects of different physical parameters on the efficiency of a generator are studied by solving the Domenicali’s equation numerically. It is found that the efficiency of a thermoelectric generator is insensitive to both the electrical resistivity and thermal conductivity. However, the efficiency ...
متن کاملQuantum Coherent Three-Terminal Thermoelectrics: Maximum Efficiency at Given Power Output
This work considers the nonlinear scattering theory for three-terminal thermoelectric devices used for power generation or refrigeration. Such systems are quantum phase-coherent versions of a thermocouple, and the theory applies to systems in which interactions can be treated at a mean-field level. It considers an arbitrary three-terminal system in any external magnetic field, including systems...
