The Effect of Width-Mismatch of Modulated Nanowaveguides on the Thermoelectric Efficiency
Micromachines, 2023 Width-modulated nanowaveguides are promising for thermoelectric efficiency enhancement because electron and phonon transport properties can be geometrically tuned for improved performance.

Impact of Fano and Breit-Wigner resonances in the thermoelectric properties of nanoscale junctions [PDF]
, 2013 We show that the thermoelectric properties of nanoscale junctions featuring states near the Fermi level strongly depend on the type of resonance generated by such states, which can be either Fano or Breit-Wigner-like.

Thermoelectric properties of Si-based thermoelectrics
Journal of Advanced Science, 1999 The thermal conductivity κ and the electric properties of Si1-xGex (x≤0.03) samples doped with Group 3B and 5B elements which were prepared by arc melting were measured as functions of carrier (or dopant) concentration n and of temperature in the range from 298K to 1273K.

Thermoelectric properties of in-plane $90^0$-bent graphene nanoribbons with nanopores [PDF]
, 2021 We study the thermoelectric performance of $90^0$-bent graphene nanoribbons containing nanopores for optimized design of multiple functional circuits including thermoelectric generators. We show that the thermal conductance of the $90^0$-bent ribbons is lower from few times to an order of magnitude compared to that of pristine armchair and zigzag ...

The thermoelectric working fluid: thermodynamics and transport [PDF]
, 2016 Thermoelectric devices are heat engines, which operate as generators or refrigerators using the conduction electrons as a working fluid. The thermoelectric heat-to-work conversion efficiency has always been typically quite low, but much effort continues ...

Thermoelectric degrees of freedom determining thermoelectric efficiency [PDF]
iScience 24, 102934 (2021), 2018 Thermal energy can be directly converted to electrical energy as a result of thermoelectric effects. Because this conversion realises clean energy technology, such as waste heat recovery and energy harvesting, substantial efforts have been made to search for thermoelectric materials.
