Controlling clouds-to-scars dislocations' transitions on spherical crystal shells
Physical Review Research, vol. 6
Abstract
The closed topology of spherical crystals renders the presence of topological defects inevitable. These defects can organize in a plethora of different structures, such as “clouds” or grain boundary “scars”, challenging for theoretical modeling and experimental visualization. Visualizing the defects by fluorescent dye adsorption, we reveal ion concentration control of a clouds-to-scars transition, which we attribute to commonly neglected defects' core energy. The consequent line tension energy probes the defects' molecular scale energetics, enabling pattern tuning for future applications. Published by the American Physical Society 2024
