non-centrosymmetric materials

Non-centrosymmetric materials are substances whose internal structure lacks a center of symmetry, meaning they are not mirror images of themselves when flipped. This asymmetry enables unique properties, such as generating electric polarization when subjected to mechanical stress (piezoelectricity) or producing circularly polarized light. These materials are vital in various technologies, including sensors, actuators, and advanced optics. Their non-centrosymmetric nature distinguishes them from symmetrical materials, allowing them to exhibit behaviors driven by their asymmetrical arrangement of atoms or molecules.
