Curvature has been an interesting and practical subject as the needs for the nanoscale materials are increased. Especially, curved structures in liquid crystal (LC) phases such as disclination lines, distortions, and focal conic defects (FCDs) have been extensively explored in micron-scale that is visible with optical microscopy. In such as special occasions of LC phase in B4 or dark conglomerate of bent-core molecules can show the curvature in nanoscale, which is resulted from sublayer structure of molecule, however these are very unusual case in LC phases. Recently, it was found that the layering structure of smectic (Sm) LC phase is thermally sublimed to form nanoscale curvatures. We explore the controllable Gaussian curvature in nanoscale using this behavior. This can be of great interest and use in further exploration of the physical properties of curvature structures of soft matters. |
