Exploring low lattice thermal conductivity materials using chemical bonding principles
Jiangang He, Yi Xia, Wenwen Lin +4
Semiconductors with very low lattice thermal conductivities are highly desired for applications relevant to thermal energy conversion and management, such as thermoelectrics and th…
Accelerated Discovery of a Large Family of Quaternary Chalcogenides with very Low Lattice Thermal Conductivity
Koushik Pal, Yi Xia, Jiahong Shen +4
The development of efficient thermal energy management devices such as thermoelectrics, barrier coatings, and thermal data-storage disks often relies on compounds that possess very…
Microscopic mechanism of unusual lattice thermal transport in TlInTe
Koushik Pal, Yi Xia, Chris Wolverton
We investigate the microscopic mechanism of ultralow lattice thermal conductivity () of TlInTe and its weak temperature dependence using a unified theory of lattice heat t…
When Band Convergence is Not Beneficial for Thermoelectrics
Junsoo Park, Max Dylla, Yi Xia +3
Band convergence is considered a clear benefit to thermoelectric performance because it increases the charge carrier concentration for a given Fermi level, which typically enhances…
Microscopic Mechanisms of Glass-Like Lattice Thermal Transport in Cubic CuSbS Tetrahedrites
Yi Xia, Vidvuds Ozolins, Chris Wolverton
Materials based on cubic tetrahedrites (CuSbS) are useful thermoelectrics with unusual thermal and electrical transport properties, such as very low and nearly…
High Thermoelectric Performance and Defect Energetics of Multi-pocketed Full-Heusler Compounds
Junsoo Park, Yi Xia, Alex Ganose +2
We report first-principles density-functional study of electron-phonon interactions and thermoelectric transport properties of full-Heusler compounds SrBiAu and SrSbAu.…
