Record‐High Thermoelectric Performance in Al‐Doped ZnO via Anderson Localization of Band Edge States

Illia Serhiienko, Andrei Novitskii, Fabian Garmroudi, Evgeny A. Kolesnikov et autres

Abstract Oxides are of interest for thermoelectrics due to their high thermal stability, chemical inertness, low cost, and eco‐friendly constituting elements. Here, adopting a unique synthesis route via chemical co‐precipitation at strongly alkaline conditions, one of the highest thermoelectric performances for ZnO …

Magnetotransport Properties of Mn2CoSb

Marina Seredina, Aleksei V. Bogach, D. Yu. Karpenkov, Vladislav L. Kurichenko et autres

So far, only basic magnetic and transport properties of Mn2CoSb Heusler alloy have been reported in the literature. In this work, we investigated magnetotransport properties of melt-spun ribbons of Mn2CoSb. The calculation of normal Hall coefficients$R_{0}$revealed a dominant role of electrons in …

Thermoelectric properties of Sm-doped BiCuSeO oxyselenides fabricated by two-step reactive sintering

Andrei Novitskii, Illia Serhiienko, S P Novikov, Kirill Kuskov et autres

Among layered oxygen-containing compounds, BiCuSeO is one of the most promising candidates for thermoelectric applications due to its intrinsically low thermal conductivity and good thermal stability. However, the rather poor electrical conductivity of pristine BiCuSeO hinders its potential. Further enhancement of the …

Thermoelectrics: Flexible Thermoelectric Polymer Composites Based on a Carbon Nanotubes Forest (Adv. Funct. Mater. 40/2018)

Khabib Yusupov, Steffi Stumpf, Shujie You, Aleksei V. Bogach et autres

In article number 1801246, Khabib Yusupov, Alberto Vomiero, and co-workers combine vertically aligned carbon nanotubes forests (VA-CNTFs) as fillers and chemical post-treatment in polymer-based high-efficiency thermoelectric composites, by dispersing VA-CNTF into a poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) matrix. An increased Seebeck coefficient (58.7 …

Flexible Thermoelectric Polymer Composites Based on a Carbon Nanotubes Forest

Khabib Yusupov, Steffi Stumpf, Shujie You, Aleksei V. Bogach et autres

Abstract Polymer‐based composites are of high interest in the field of thermoelectric (TE) materials because of their properties: abundance, low thermal conductivity, and nontoxicity. In applications, like TE for wearable energy harvesting, where low operating temperatures are required, polymer composites demonstrate compatible …
