Nucleation Front Proliferation in Bi-modal PCBM Crystals and a Crystal Fan – Axial Morphological Transition.

Abstract

This paper analyses crystal properties of PCBM when annealed in a bilayer with PS on the top. There are intriguing formations and definite thresholds to the varying reproducible morphologies found. This paper suggests that the PS layer greatly influences PCBM crystal nucleation rate and final morphology.
