A novel growth mode, characterized by absence of grain coarsening, Ostwald ripening, and secondary nucleation, is observed for a polar conjugated molecule, viz. tris-(8-hydroxyquinoline) aluminum (III) (Alq(3)), grown onto an apolar silicon substrate by high-vacuum sublimation. It results in correlated droplet patterns on a mesoscopic length scale with narrow size distribution, which can be tuned by means of the deposition time t and substrate temperature T-s. A comprehensive analysis of the results is obtained on the basis of a capture zone model.
