Abstract
A method for demonstrating the scattering of the primary electron beam in the presence of a gas has been developed. A self‐assembled decanethiol monolayer is damaged by primary beam electrons. The damaged portion of the mono‐layer is exchanged with another thiol‐containing molecule by immersion in solution. The resulting film is imaged using a secondary ion mass spectrometer. Three‐dimensional reconstruction of the data yields a representation of scattered electrons in the gaseous environment of the environmental scanning electron microscope.
