Particle Shape Controls Defects in Colloidal Crystals on Spheres
Analysis
Key Takeaways
- •Particle shape significantly impacts defect formation in colloidal crystals on spherical surfaces.
- •Cube particles form square assemblies with evenly distributed defects, maximizing entropy.
- •Varying particle shape allows for control over defect distribution and symmetry.
- •The findings have implications for programmable defect generation and vesicle buckling.
“Cube particles form a simple square assembly, overcoming lattice/topology incompatibility, and maximize entropy by distributing eight three-fold defects evenly on the sphere.”
