Thermoelectric properties of InAs nanowires from full-band atomistic simulations
Damiano Archetti, Neophytos Neophytou
In this work we theoretically explore the effect of dimensionality on the thermoelectric power factor of InAs nanowires by coupling atomistic tight-binding calculations to the Line…
Hierarchically nanostructured thermoelectric materials: Challenges and opportunities for improved power factors
Neophytos Neophytou, Vassilios Vargiamidis, Samuel Foster +9
The field of thermoelectric materials has undergone a revolutionary transformation over the last couple of decades as a result of the ability to nanostructure and synthesize myriad…
Berry curvature, orbital magnetization, and Nernst effect in biased bilayer WSe
Vassilios Vargiamidis, P. Vasilopoulos, M. Tahir +1
A valley-contrasting Berry curvature in bilayer transition metal dichalcogenides with spin-orbit coupling can generate valley magnetization when the inversion symmetry is broken, f…
Thermoelectric power factor under strain-induced band-alignment in the half-Heuslers NbCoSn and TiCoSb
Chathurangi Kumarasinghe, Neophytos Neophytou
Band convergence is an effective strategy to improve the thermoelectric performance of complex bandstructure thermoelectric materials. Half-Heuslers are good candidates for band co…
Heat current anticorrelation effects leading to thermal conductivity reduction in nanoporous Si
Laura de Sousa Oliveira, S. Aria Hosseini, Alex Greaney +1
Prevailing nanostructuring strategies focus on increasing phonon scattering and reducing the mean-free-path of phonons across the spectrum. In nanoporous Si materials, for example,…
Ultra-High Thermoelectric Power Factors in Narrow Gap Materials with Asymmetric Bands
Patrizio Graziosi, Neophytos Neophytou
We theoretically unveil the unconventional possibility to achieve extremely high thermoelectric power factors in lightly doped narrow gap semiconductors with asymmetric conduction/…
