In the present work we study the polar properties of domain walls using a recently developed method of combining layer group analysis with order parameter symmetry [Schranz et al. PRB 100 (2019) 184105]. Using this method we obtain a detailed overvie

We use optical pump—terahertz (THz) probe spectroscopy to investigate ultrafast sheet conductivity dynamics in various epitaxial graphene layers grown on SiC. Inhomogeneities in graphene layers developed during the growth are at the origin of confi

The polar properties of antiphase boundaries (APBs) in PbZrO$_3$ are analyzed in detail using a recently developed layer group approach in order parameter space and compared with the results from Landau-Ginzburg free energy description. It is shown t

Based on a recently developed combination of layer group analysis with order-parameter symmetry, we study the polarity of antiphase domain boundaries (APBs) and ferroelastic twin boundaries (TBs) in $\mathrm{Sr}\mathrm{Ti}{\mathrm{O}}_{3}$. In additi

Domain boundaries and other twin boundaries in crystalline materials are receiving increasing interest. They can carry unique functional properties, which in many cases are absent in the surrounding bulk material. One such property of domain boundari

Dielectric properties of laminates composed of two regularly arranged rhombohedral ferroelectric domains are calculated both analytically and numerically. Two structures are considered; in the first one, the adjacent polarizations make the angle 109

Films of colloidal TiO2 nanoparticles are widely used in photovoltaic and photocatalytic applications, and the nature of electrical conductivity in such materials is therefore of both fundamental and practical interest. The conductive properties of c
