First-principles study of thermal transport properties in the two- and three-dimensional forms of Bi2O2Se

The intralayer opposite phonon vibrations in the monolayer Bi2O2Se greatly suppress the thermal transport and lead to lower lattice thermal conductivity than its bilayer and bulk forms.

Thermal Transport Properties

Highly dense pore structure was generated by simple sequential routes using NaCl and PVA as porogens in conventional PbTe thermoelectric materials, and the effect of pores on thermal transport properties was investigated. Compared with the pristine PbTe, the lattice thermal conductivity values of pore-generated PbTe polycrystalline bulks were significantly reduced due to the enhanced phonon scattering by mismatched phonon modes in the presence of pores (200 nm–2 μm) in the PbTe matrix. We obtained extremely low lattice thermal conductivity (~0.56 W m−1 K−1at 773 K) in pore-embedded PbTe bulk after sonication for the elimination of NaCl residue.
