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…
On the Lorenz number of multi-band materials
Mischa Thesberg, Hans Kosina, Neophytos Neophytou
There are many exotic scenarios where the Lorenz number of the Wiedemann-Franz law is known to deviate from expected values. However, in conventional semiconductor systems, it is a…
On the effectiveness of the thermoelectric energy filtering mechanism in low-dimensional superlattices and nano-composites
Mischa Thesberg, Hans Kosina, Neophytos Neophytou
Electron energy filtering has been suggested as a promising way to improve the power factor and enhance the ZT figure of merit of thermoelectric materials. In this work we explore…
The influence of non-idealities on the thermoelectric power factor of nanostructured superlattices
Mischa Thesberg, Mahdi Pourfath, Hans Kosina +1
Cross-plane superlattices composed of nanoscale layers of alternating potential wells and barriers have attracted great attention for their potential to provide thermoelectric powe…
Low-dimensional phonon transport effects in ultra-narrow, disordered graphene nanoribbons
Hossein Karamitaheri, Mahdi Pourfath, Hans Kosina +1
We investigate the influence of low-dimensionality and disorder in phonon transport in ultra-narrow armchair graphene nanoribbons (GNRs) using non-equilibrium Greens function (NEGF…
Gated Si nanowires for large thermoelectric power factors
Neophytos Neophytou, Hans Kosina
We investigate the effect of electrostatic gating on the thermoelectric power factor of p-type Si nanowires (NWs) of up to 20nm in diameter in the [100], [110] and [111] crystallog…
