Off-resonant light-induced topological phase transition and thermoelectric transport in semi-Dirac materials
Vassilios Vargiamidis, P. Vasilopoulos, Neophytos Neophytou
We show that a semi-Dirac (SD) system with an inversion symmetry breaking mass exhibits a topological phase transition when irradiated with off-resonant light. Using Floquet theory…
Energy Filtering in Doping Modulated Nanoengineered Thermoelectric Materials: A Monte Carlo Simulation Approach
Pankaj Priyadarshi, Vassilios Vargiamidis, Neophytos Neophytou
Using Monte Carlo electronic transport simulations, coupled self-consistently with the Poisson equation for electrostatics, we explore the thermoelectric power factor of nanoengine…
Super-suppression of long wavelength phonons in constricted nanoporous geometries
Alex Greaney, S. Aria Hosseini, Laura de Sousa Oliveira +2
In a typical semiconductor material, the majority of heat is carried by long wavelength, long mean-free-path phonons. Nanostructuring strategies to reduce thermal conductivity, a p…
The role of electronic bandstructure shape in improving the thermoelectric power factor of complex materials
Patrizio Graziosi, Neophytos Neophytou
The large variety of complex electronic structure materials and their alloys, offer highly promising directions for improvements in thermoelectric (TE) power factors (PF). Their el…
Electronic transport computation in thermoelectric materials: From ab initio scattering rates to nanostructures
Neophytos Neophytou, Pankaj Priyadarshi, Zhen Li +1
Over the last two decades a plethora of new thermoelectric materials, their alloys, and their nanostructures were synthesized. The ZT figure of merit, which quantifies the thermoel…
Computationally efficient Monte Carlo electron transport algorithm for nanostructured thermoelectric material configurations
Pankaj Priyadarshi, Neophytos Neophytou
Monte Carlo statistical ray-tracing methods are commonly employed to simulate carrier transport in nanostructured materials. In the case of a large degree of nanostructuring and un…
