Achieving ultra-high power factor in Sb2Te2Se via valence band convergence
Mohammad Rafiee Diznab, Iraj Maleki Shahrivar, S. Mehdi Vaez Allae +2
An efficient approach to improve the thermoelectric performance of materials is to converge their electronic bands, which is known as band engineering. In this regard, lots of effo…
Leveraging Electron-Phonon Interaction to Enhance Thermoelectric Power Factor in Graphene-Like Semimetals
Yi Xia, Junsoo Park, Vidvuds Ozoliņš +1
Electron-phonon interaction (EPI) is presumably detrimental for thermoelectric performance in semiconductors because it limits carrier mobility. Here we show that enhanced EPI with…
Impact of Temperature-Dependent Rattling Phonons on Lattice Dynamics and Thermal Transport in AgGeP
Yi Xia, Vidvuds Ozoliņš
Crystalline compounds exhibiting low-frequency rattling phonons constitute an important class of high-performance thermoelectrics owning to their intrinsically very low lattice the…
Computational prediction of lattice thermal conductivity -- a comparison of molecular dynamics and Boltzmann transport approaches
Marcello Puligheddu, Yi Xia, Maria K. Y. Chan +1
The predictive modeling of lattice thermal conductivity is of fundamental importance for the understanding and design of materials for a wide range of applications. Two major appro…
