Synergistic effect of workfunction and acoustic impedance mismatch for improved thermoelectric performance in GeTe/WC composite

Autor: Kumar, Ashutosh, Bhumla, Preeti, Kosonowski, Artur, Wolski, Karol, Zapotoczny, Szczepan, Bhattacharya, Saswata, Wojciechowski, Krzysztof

Publikováno v: ACS Applied Materials & Interfaces 14(39) (2022) 44527-44538

The preparation of composite materials is promising for concurrent optimization of electrical and thermal transport properties to realize an improved thermoelectric (TE) performance. We report the effect of work function and acoustic impedance mismat

Effective Thermal Conductivity of SrBi$_4$Ti$_4$O$_{15}$-La$_{0.7}$Sr$_{0.3}$MnO$_3$ Oxide composite: Role of Particle Size and Interface Thermal Resistance

Autor: Kumar, Ashutosh, Kosonowski, Artur, Wyzga1, Piotr, Wojciechowski, Krzysztof T.

Publikováno v: Journal of the European Ceramic Society 41(1) (2021) 451-458

We present a novel approach to reduce the thermal conductivity ($\kappa$) in thermoelectric composite materials using acoustic impedance mismatch and the Debye model. Also, the correlation between interface thermal resistance (R$_{int}$) and the part

Report

Thermal conductivity of PbTe-CoSb3 bulk polycrystalline composite: the role of microstructure and interface thermal resistance

Autor: Kosonowski, Artur, Kumar, Ashutosh, Parashchuk, Taras, Cardoso-Gil, Raul, Wojciechowski, Krzysztof T.

Publikováno v: Dalton Transactions 50(4) (2021) 1261-1273

Systematic experimental and theoretical research on the role of microstructure and interface thermal resistance on the thermal conductivity of the PbTe-CoSb3 bulk polycrystalline composite is presented. In particular, the correlation between the part
