Exceptional thermoelectric properties in NaTlSb enabled by quasi-1D band structure
Øven A. Grimenes, Ole M. Løvvik, Kristian Berland
Materials with reduced dimensionality offer beneficial density-of-states (DOS) profiles for thermoelectric energy conversion, but can be impractical in realistic devices. Encouragi…
Thermoelectric transport of strained CsKSb: The role of electron velocities and scattering within extended Fermi surfaces
Øven A. Grimenes, G. Jeffrey Snyder, Ole M. Løvvik +1
In this first-principles study, we investigated the thermoelectric properties of the full-Heusler compound CsKSb at different compressive strains. This material exhibits a vale…
Lattice Thermal Conductivity from First Principles and Active Learning with Gaussian Process Regression
Rasmus Tranås, Ole Martin Løvvik, Kristian Berland
The lattice thermal conductivity () is a key materials property in power electronics, thermal barriers, and thermoelectric devices. Identifying a wide pool of compounds w…
High Entropy Alloy CrFeNiCoCu sputtered films
J. Mayandi, M. Schrade, P. Vajeeston +10
High entropy alloy(HEA) films of CrFeCoNiCu were prepared by sputtering, their structure was characterized, and their electric properties measured by temperature dependent Hall and…
Discarded gems: Thermoelectric performance of materials with band gap emerging at the hybrid-functional level
Kristian Berland, Ole Martin Løvvik, Rasmus Tranås
A finite electronic band gap is a standard filter in high-throughput screening of materials using density functional theory (DFT). However, because of the systematic underestimatio…
Lattice thermal conductivity of half-Heuslers with density functional theory and machine learning: Enhancing predictivity by active sampling with principal component analysis
Rasmus Tranås, Ole Martin Løvvik, Oliver Tomic +1
Low lattice thermal conductivity is essential for high thermoelectric performance of a material. Lattice thermal conductivity is often computed using density functional theory (DFT…
