Domain boundaries and other twin boundaries in crystalline materials arereceiving increasing interest. They can carry unique functional properties,which in many cases are absent in the surrounding bulk material. One suchproperty of domain boundaries can be their electric polarity. Phenomenologicalinsight in the polarity of domain boundaries was so far based either on theknowledge of the order parameter and the form of Landau-Ginzburg free energyfunctional, or on the knowledge of the symmetry of the domain boundaries. Inthe present work we show on the concrete examples of potassium thiocyanate(KSCN) and lacunar spinel crystals, that the concept of the primaryorder-parameter can help to find the layer group describing the maximalpossible symmetry of a given domain boundary. Combination of layer group andorder parameter symmetries is then employed to clarify the nature of thepolarity of domain boundaries.
