ABSTRACT
Exoelectrons were emitted from a 99.9999% pure Al tip by applying an electric field as a stimulus. This occurred at lower voltages than that necessary for field emission of electrons. Field-stimulated exoelectron emission showed a characteristic storage effect in accordance with the time interval of applied voltage pulses. Based upon this storage effect and a computer calculation of the field strength at the apex of the tip, we show by analytical discussions that exoelectrons are emitted by tunneling, not by the Schottky effect.
