Surface Contamination by Ion Bombardmentombardment can be explained by the larger cross section for polymerization of organic molecules adsorbed on the surface. Furthermore, it is ascertained that heating the substrate or using a cold trap surrounding the substrate can effectively reduce the contamination growth.
