Lattice thermal conductivities of two SiO${}_2$ polymorphs by first-principles calculation and phonon Boltzmann transport equation

Keiyu Mizokami, Atsushi Togo, Isao Tanaka

Lattice thermal conductivities of two SiO${}_2$ polymorphs, i.e., $\alpha$-quartz (low) and $\alpha$-cristobalite (low), were studied using first-principles anharmonic phonon calculation and l…
