Theoretical studies of crystals with intrinsically ultralow lattice thermal conductivity

第六届海内外中华青年材料科学技术研讨会(2015)——In the important widely-studied class of thermoelectric materials, it has been long standing problem to improve the energy conversion efficiencies. The talk provides one solution to this problem by looking for perfect crystals with intrinsically low lattice thermal conductivity. The lattice thermal conductivity evaluation method is based on the combination of first-principle calculations of the vibrational properties within the quasi-harmonic approximation and the Debye-Callaway model.
