Query: Thermal conductivity of the quasi-1D materials TaSe3 and ZrTe3   The high breakdown current densities and resilience to scaling of the
metallic transition metal trichalcogenides TaSe3 and ZrTe3 make them of
interest for possible interconnect applications, and it motivates this study of
their thermal conductivities and phonon properties. These crystals consist of
planes of strongly bonded one-dimensional chains more weakly bonded to
neighboring chains. Phonon dispersions and the thermal conductivity tensors are
calculated using density functional theory combined with an iterative solution
of the phonon Boltzmann transport equation. The phonon velocities and the
thermal conductivities of TaSe3 are considerably more anisotropic than those of
ZrTe3. The maximum LA velocity in ZrTe3 occurs in the cross-chain direction,
and this is consistent with the strong cross-chain bonding that gives rise to
large Fermi velocities in that direction. The thermal conductivities are
similar to those of other metallic two-dimensional transition metal
dichalcogenides. At room temperature, a significant portion of the heat is
carried by the optical modes. In the low frequency range, the phonon lifetimes
and mean free paths in TaSe3 are considerably shorter than those in ZrTe3. The
shorter lifetimes in TaSe3 are consistent with the presence of lower frequency
optical branches and zone-folding features in the acoustic branches that arise
due to the doubling of the TaSe3 unit cell within the plane.
