Atomic-scale tunable phonon transport at tailored grain boundaries and Their Impact on Thermal Conductivity
Xiaowang Wang, Chaitanya A. Gadre, Wanjuan Zou +16
Grain boundaries (GBs) strongly influence thermal transport in crystalline solids by disrupting lattice periodicity and scattering phonons. Due to the atomic-level disorder and str…

Inelastic electron scattering at large angles: the phonon polariton contribution
Hongbin Yang, Paul Zeiger, Andrea Konečná +11
We explore the inelastic electron scattering in SrTiO3, PbTiO3, and SiC in their phonon energy range, challenging the assumption that phonon polaritons are excluded at large angles…
