Randomness in self-assembled colloidal crystals can widen photonic band gaps through particle shape and internal structure
Duanduan Wan, Sharon C. Glotzer
Using computer simulations, we explore how thermal noise-induced randomness in a self-assembled photonic crystal affects its photonic band gaps (PBGs). We consider a two-dimensiona…

FCC-to-BCC phase transitions in convex and concave hard particle systems
Duanduan Wan, Chrisy Xiyu Du, Greg van Anders +1
Particle shape plays an important role in the phase behavior of colloidal self-assembly. Recent progress in particle synthesis has made particles of polyhedral shapes and dimpled s…
