A numerical framework using self-consistent phonon renormalization extended to third- and fourth-order force constants is applied to phonon dispersion, linewidths, and temperature-dependent lattice thermal conductivity in NaCl, AgI, cBN, and 3C-SiC.
Spectroscopic measurements on selenium thin films indicate that structural disorder is processing-dependent rather than intrinsic and correlates with reduced carrier lifetime and open-circuit voltage in photovoltaic applications.
