We show that the commonly used lowest-order theory of phonon-phonon interactions
frequently fails to accurately describe the anharmonic phonon decay rates and thermal …

Current phonon transport theory based on ground-state calculations has been successful in
predicting thermal conductivity at room and medium temperatures but may misrepresent …

While using first-principles-based Boltzmann transport equation approach to predict the
thermal conductivity of crystalline semiconductor materials has been a routine, the validity of …

Lattice thermal conductivities of zirconium carbide (ZrC x, x= 1, 0.75 and 0.5) ceramics with
different carbon vacancy concentrations were calculated using a combination of first …

Zirconium carbide is a compound widely used in cutting tools, nuclear reactors, field emitter
