Effective masses in complex band structures, a code to extract them
Patrizio Graziosi, Neophytos Neophytou
A code to extract the effective masses for the density of states and the conductivity of an arbitrary band structure is presented and the meaning of these masses for the band struc…
Impact of the scattering physics on the power factor of complex thermoelectric materials
Patrizio Graziosi, Chathurangi Kumarasinghe, Neophytos Neophytou
We assess the impact of the scattering physics assumptions on the thermoelectric properties of five Co-based p-type half-Heusler alloys by considering full energy-dependent scatter…
Thermal rectification optimization in nanoporous Si using Monte Carlo simulations
Dhritiman Chakraborty, Joshua Brooke, Nick C S Hulse +1
We investigate thermal rectification in nanoporous silicon using a semi-classical Monte Carlo (MC) simulation method. We consider geometrically asymmetric nanoporous structures, an…
Modelling thermoelectric performance in nanoporous nanocrystalline silicon
Laura de Sousa Oliveira, Vassilios Vargiamidis, Neophytos Neophytou
Introducing hierarchical disorder from multiple defects into materials through nanostructuring is one of the most promising directions to achieve extremely low thermal conductiviti…
Theoretical model for the Seebeck coefficient in superlattice materials with energy relaxation
Vassilios Vargiamidis, Mischa Thesberg, Neophytos Neophytou
We present an analytical model for the Seebeck coefficient S of superlattice materials that explicitly takes into account the energy relaxation due to electron-optical phonon (e-ph…
Large-scale molecular dynamics investigation of geometrical features in nanoporous Si
Laura de Sousa Oliveira, Neophytos Neophytou
Nanoporous materials are of broad interest for various applications, in particular advanced thermoelectric materials. The introduction of nanoscale porosity, even at modest levels,…
