Kinetic roughening of aggregates of patchy colloids with strong and weak bonds
arXiv:1407.2374 · doi:10.1209/0295-5075/107/56002
Abstract
We study the irreversible aggregation of films of patchy spherical colloids with directional and selective interactions. We report a crossover of the interfacial roughening from the Kardar-Parisi-Zhang (KPZ) to the KPZ with quenched disorder (KPZQ) universality class when the difference between the strong and weak bonds is sufficiently large. We calculate the critical exponents and identify the crossover between the two regimes.
