In the context of the theory of charged surfaces, this paper re-assesses the role of field-ion appearance energy measurements in deriving information about electrical-surface position. It brings together and summarises relevant basic theory, uses existing experimental data and recent theoretical results to obtain revised numerical estimates of repulsion distance, notes some anomalies, and defines a scientific challenge.
