Low lattice thermal conductivity (κl) is a crucial factor for higher figure-of merit and hence the efficiency of thermoelectric generators. There are several reports on intrinsically low κl values in two-dimensional (2D) van der Waals materials usi

A first-principles method is presented to calculate elastic constants up to the fourth order of crystals with the cubic and hexagonal symmetries. The method relies on the numerical differentiation of the second Piola-Kirchhoff stress tensor and a den

Tin chalcogenides (SnS, SnSe, and SnTe) are the emerging key thermoelectric (TE) materials with low toxicity and eco-friendly nature, which could serve as an alternative to the toxic lead-based alloys. The Sn-based alloys are also found to have impro

In this work we investigate the role of quartic anharmonicity on the lattice- and thermo-dynamic properties of rectangular ( γ ) and square (β) phases of two-dimensional (2D) SnTe monolayer (ML) by using self-consistent phonon (SCP) theory, based o

The structural, electronic and thermoelectric properties of Pb1−xSnxTe (x = 0, 0.25, 0.5, 0.75, 1) alloys are investigated using density functional theory and the semi-classical Boltzmann transport theory. Both PbTe and SnTe binary alloys exhibit a

Lead and tin chalcogenides have been studied widely due to their promising thermoelectric (TE) properties. Further enhancement in their TE efficiency has been reported upon the reduction of the dimension, which is an important feature in modern devic

Two-dimensional (2D) ZrS2 monolayer (ML) has emerged as a promising candidate for thermoelectric (TE) device applications due to its high TE figure of merit, which is mainly contributed by its inherently low lattice thermal conductivity. This work in
