Diffraction and near-zero transmission of flexural phonons at graphene grain boundaries
Edit E. Helgee, Andreas Isacsson
Graphene grain boundaries are known to affect phonon transport and thermal conductivity, suggesting that they may be used to engineer the phononic properties of graphene. Here, the…

Scattering of flexural acoustic phonons at grain boundaries in graphene
Edit E. Helgee, Andreas Isacsson
We investigate the scattering of long-wavelength flexural phonons against grain boundaries in graphene using molecular dynamics simulations. Three symmetric tilt grain boundaires a…

Oxygen vacancy segregation and space-charge effects in grain boundaries of dry and hydrated BaZrO3
B. Joakim Nyman, Edit E. Helgee, Göran Wahnström
A space-charge model is applied to describe the equilibrium effects of segregation of double-donor oxygen vacancies to grain boundaries in dry and wet acceptor-doped samples of the…
