non-centrosymmetry

Non-centrosymmetry refers to a property of certain materials that lack a center of symmetry in their structure. In simpler terms, if you imagine an object, a center of symmetry would mean that if you flip it around a central point, it looks the same. Non-centrosymmetric materials do not have this property; flipping them does not yield an identical view. This characteristic is significant in various fields, particularly in physics and materials science, as it influences behaviors like piezoelectricity, where materials generate electric charge when mechanically stressed.
