On-chip detection of anisotropic thermopolarization in quartz
Shuichi Iwakiri, Yasumitsu Miyata, Takao Mori
Temperature gradients are widely used to drive and probe transport phenomena in solids, forming the basis of heat-to-charge conversion processes. In typical experiments, local heat…
Observation of universal thermopolarization effect in insulators
Shuichi Iwakiri, Yasumitsu Miyata, Takao Mori
Heat-to-charge conversion has traditionally been realized via the Seebeck effect in conductors and pyroelectricity in polar insulators. Here, we demonstrate that temperature gradie…
-type RuTiHfSi full-Heusler bulk thermoelectrics with
Fabian Garmroudi, Illia Serhiienko, Michael Parzer +4
Heusler compounds have emerged as important thermoelectric materials due to their combination of promising electronic transport properties, mechanical robustness and chemical stabi…
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…
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…
Iterative composition optimization in FeVAl-based thin-film thermoelectrics using single-target sputtering
Alexander Riss, Ellena Lasisch, Simon Podbelsek +6
Magnetron sputtering inherently exhibits the advantage of dislodging particles from the target in a ratio equivalent to the target stoichiometry. Nevertheless, film compositions of…
