Breaking the Wiedemann-Franz limit in thermoelectrics via separated flat bands
Illia Serhiienko, Fabian Garmroudi, Stefan Enzner +3
Controlling the charge and spin degrees of freedom of electrons in solids has been at the heart of condensed-matter science for centuries. One hallmark of metallic conduction is th…
-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…
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…
High thermoelectric power factor through topological flat bands
Fabian Garmroudi, Illia Serhiienko, Simone Di Cataldo +11
Thermoelectric (TE) materials are useful for applications such as waste heat harvesting or efficient and targeted cooling. While various strategies towards superior thermoelectrics…
Thermoelectric properties of Sm-doped BiCuSeO oxyselenides fabricated by two-step reactive sintering
Andrei Novitskii, Illia Serhiienko, Sergey Novikov +10
Among layered oxygen-containing compounds, BiCuSeO is one of the most promising candidates for thermoelectric applications due to its intrinsically low thermal conductivity and goo…
Influence of Bi substitution with rare-earth elements on the transport properties of BiCuSeO oxyselenides
Andrei Novitskii, Illia Serhiienko, Sergey Novikov +10
In this study, we demonstrate that introducing of rare-earth elements, = La or Pr, into the Bi-O charge reservoir layer of BiCuSeO leads to an increase of both, the charge carr…
Ultrafast synthesis of Pb-doped BiCuSeO oxyselenides by high-energy ball milling
Andrei Novitskii, Illia Serhiienko, Evgeny Kolesnikov +3
We report on the direct ultrafast synthesis of Pb-doped BiCuSeO oxyselenides by high-energy ball milling. We show that, contrary to the mechanical alloying sintering routes used in…
