Enhanced thermoelectric performance of N-type Bi2Te2.7Se0.3-based materials by superparamagnetic Fe3O4 nanoparticles

Tuning the lattice thermal conductivity of Sb2Te3 by Cr doping: a deep potential molecular dynamics study

“…However, these internally coupled parameters (S, s, and k e ) make it extremely challenging to optimize the PF and k e simultaneously. In contrast, the lattice thermal conductivity (k l ) is a comparatively independent parameter and can be effectively regulated by various means, such as introducing point defects, [4][5][6] grain boundaries, [7][8][9] dislocation arrays, [10][11][12] and so on. Element doping, which can introduce point defects and grain boundaries into materials, is an effective way to reduce thermal conductivity by enhancing phonon scattering.…”

Enhancement of Thermoelectric Properties of p-Type Bi0.4Sb1.6Te3 Incorporated by BaFe12O19 Magnetic Nanoparticles

“…Unfortunately, their relatively low ZT values have limited their extensive use. Recent studies have focused on optimization strategies that have been adopted to improve the thermoelectric performance, including carrier filtering engineering, band engineering, high-entropy engineering, , and phonon scattering engineering in applications, such as hierarchical microstructures, lattice anharmonicity, and magnetic particles scattering. ,− …”
