Absorption of an Electron by a Dielectric Wall. Bronold, F. & Fehske, H. *Physical Review Letters*, 115(22):225001, November, 2015. Paper doi abstract bibtex We introduce a method for calculating the probability with which a low-energy electron hitting the wall of a bounded plasma gets stuck in it and apply the method to a dielectric wall with positive electron affinity smaller than the band gap using MgO as an example. In accordance with electron beam scattering data we obtain energy-dependent sticking probabilities significantly less than unity and question thereby for electrons the perfect absorber assumption used in plasma modeling.
