Crystal phenomena as a research area investigates the physical behaviors and properties that arise from the ordered atomic or molecular arrangements in crystalline solids, including symmetry-governed effects and defect-related responses. It encompasses studies of phase transitions, lattice dynamics, crystallographic defects (dislocations, vacancies, interfaces), anisotropic mechanical, thermal, and electronic behavior, as well as optical and dielectric responses governed by crystal symmetry and band structure. The field integrates experimental techniques such as X-ray and neutron diffraction, electron microscopy, and spectroscopies with theoretical and computational methods to elucidate structure–property relationships, enabling the design and control of functional materials in electronics, photonics, mechanics, and quantum technologies.
Twinned nanoparticles have regions of clear symmetry that share the same crystal lattice, separated by a clear boundary. Changing the twin structure can affect the properties of the nanoparticles, which makes controlling ...
