A direct observation of the influence of an externally applied electrostatic field on the sublimation steps on (100) surfaces of KCl is reported. Typically, round-cornered square spirals were found to be distorted into round-cornered rhombical spirals in the presence of a field. The results are interpreted in terms of charged kinks on the surface.
