Abstract
What's the charge? X‐ray photoelectron spectroscopy was used to determine the charge state and dynamics of charge build‐up and decay on a thin poly(methyl methacrylate) film. The film is initially negatively charged to around −2 V and becomes progressively positively charged during the course of the XPS analysis.
