Attaining Low Lattice Thermal Conductivity in Half-Heusler Sublattice Solid Solutions: Which Substitution Site Is Most Effective?
Tranås, Rasmus André; Løvvik, Ole Martin; Berland, Kristian (Peer reviewed; Journal article, 2022)Low thermal conductivity is an important materials property for thermoelectricity. The lattice thermal conductivity (LTC) can be reduced by introducing sublattice disorder through partial isovalent substitution. Yet, ... -
Discarded gems: Thermoelectric performance of materials with band gap emerging at the hybrid-functional level
Berland, Kristian; Løvvik, Ole Martin; Tranås, Rasmus André (Peer reviewed; Journal article, 2021)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 underestimation of band gaps in standard DFT approximations, ... -
Identifying Materials with Low Lattice Thermal Conductivity Using Machine Learning and Computational Modeling
Tranås, Rasmus André (Phd Thesis;2023:13, Doctoral thesis, 2023)Lattice thermal conductivity is a key materials property in applications related to thermal functionality, such as thermal barrier coatings, thermal conductors in microelectronics, and solid-state waste-heat recovery ... -
Lattice thermal conductivity of half-Heuslers with density functional theory and machine learning: Enhancing predictivity by active sampling with principal component analysis
Tranås, Rasmus André; Løvvik, Ole Martin; Tomic, Oliver; Berland, Kristian (Peer reviewed; Journal article, 2021)Low lattice thermal conductivity is essential for high thermoelectric performance of a material. Lattice thermal conductivity is often computed using density functional theory (DFT), typically at a high computational cost. ... -
Screening of thermoelectric performance of half-Heusler materials and their alloys from first principles
Grimenes, Øven Andreas (Master thesis, 2021)Thermoelectric (TE) generators have seen a lot of renewed interest over the last years. Along with increasing computational power, the approach in the search for new TE materials has seen a shift to first principle ...
