Two-dimensional (2D) materials exhibit a wide range of atomic structures, compositions, and
associated versatility of properties. Furthermore, for a given composition, a variety of …

Thermoelectric materials enable the direct conversion between waste heat and electric
energy, playing an important role in alleviating energy crisis. Many excellent thermoelectrics …

Lattice vibrations in crystalline materials generate phonons as heat carriers for heat
conduction, and the phonon dispersion (energy versus momentum) is fundamentally …

High Seebeck coefficient by creating large density-of-states effective mass through either
electronic structure modification or manipulating nanostructures is commonly considered as …

Thermoelectric transport properties of p-type PbTe: Na, with high hole concentrations of
approximately 1020 cm− 3, are reinvestigated from room temperature to 750 K. The greatly …

PbSe was expected to have a smaller bandgap and higher thermalconductivity than PbTe.
Instead, these values are about the same at high temperature leading to comparable …

PbSe is a surprisingly good thermoelectric material due, in part, to its low thermal
conductivity that had been overestimated in earlier measurements. The thermoelectric figure …

The recent discoveries of novel nanocomposite and doped lead chalcogenide-based
thermoelectric materials have attracted great interest. These materials exhibit low thermal …

Forming solid solutions has long been considered an effective approach for good
thermoelectrics because the lattice thermal conductivities are lower than those of the …

The electronic energy band structure, density of states (DOS) and charge density contour of
KNbO 3 in the paraelectric cubic phase have been studied using the full-potential linearized …
