• Center shift
• Kinetic Monte Carlo simulation
• Template-induced growth

In this paper, the center shift of organic particles on template-induced surface is systematically studied by a series of kinetic Monte Carlo simulations. The morphology evolution of center shift, the dependence of center deviation on interactions and the effects of geometrical sizes are obtained. Based on the morphology evolution of center shift, two different mechanisms are proposed, i.e. nucleation deviation and growth deviation. The former is mainly induced by the lateral nucleation of deposited particles, and the latter is mainly determined by the randomly diffusion motion of deposited particles. The two mechanisms present a significant difference for the evolution of center deviation. Based on the details of the two mechanisms, a possible method for reducing the center deviation is also supplied in the simulation.
