Monte Carlo study of crystalline order and defects on weakly curved surfaces
Monte Carlo study of crystalline order and defects on weakly curved surfaces
We numerically study the ground states of particles interacting via a repulsive Yukawa potential on two rigid substrates shaped as isolated and periodically arranged bumps characterized by a spatially varying Gaussian curvature. Below a critical aspect ratio that describes the substrate deformation, the lattice is frustrated, but defect free. A …
