Bi–Zn codoping promotes valence band convergence and strengthens multiple defect-phonon scattering in GeTe, leading to obviously improved thermoelectric properties.
The layered structure, and presence of heavier elements Rb/Cs and Sb induce high anharmonicity, low Debye temperature, intense phonon scattering, and hence, low lattice thermal conductivity.
Several endeavors were adapted to improve the thermoelectric performance of SnTe as a substitute of toxic PbTe and booming approaches comprise introduction of nanostructuring, resonance states, valence band convergence and...
In this study, we, for the first time, report a high Cu solubility of 11.8% in single crystal SnSe microbelts synthesized via a facile solvothermal route.
Remarkable enhancement of the Seebeck coefficient of an Sn rich Sn1−xPbxTe system due to the synergistic effect of resonance level formation and valence band convergence.
First-principles predictions of low lattice thermal conductivity and high thermoelectric performance of AZnSb (A = Rb, Cs)
