Heusler compounds have emerged as important thermoelectric materials due to their combination of promising electronic transport properties, mechanical robustness and chemical stabi…
Energy filtering-induced ultrahigh thermoelectric power factors in NiGe
Fabian Garmroudi, Simone Di Cataldo, Michael Parzer +15
Traditional thermoelectric materials rely on low thermal conductivity to enhance their efficiency but suffer from inherently limited power factors. Novel pathways to optimize elect…
Thermoelectric transport in RuTiSi full-Heusler compounds
Fabian Garmroudi, Michael Parzer, Takao Mori +2
Heusler compounds with six valence electrons per atom have attracted interest as thermoelectric materials owing to their semimetallic and semiconducting properties. Here, we theore…
Vacancy-induced pseudo-gap formation in antiferromagnetic CrZnSb
Michael Parzer, Fabian Garmroudi, Herwig Michor +7
Structural defects are important for both solid-state chemistry and physics, as they can have a significant impact on chemical stability and physical properties. Here, we identify…
Decoupled charge and heat transport for high-performance FeVAl composite thermoelectrics
Fabian Garmroudi, Illia Serhiienko, Michael Parzer +16
Decoupling charge and heat transport is essential for optimizing thermoelectric materials. Strategies to inhibit lattice-driven heat transport, however, also compromise carrier mob…
