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…
Real-Space Visualization of Frequency-Dependent Anisotropy of Atomic Vibrations
Xingxu Yan, Paul M. Zeiger, Yifeng Huang +11
The underlying dielectric properties of materials, intertwined with intriguing phenomena such as topological polariton modes and anisotropic thermal conductivities, stem from the a…
Evidence for a quantum-spin-Hall phase in graphene decorated with Bi2Te3 nanoparticles
K. Hatsuda, H. Mine, T. Nakamura +4
Realization of the quantum-spin-Hall effect in graphene devices has remained an outstanding challenge dating back to the inception of the field of topological insulators. Graphene'…
