Abstract: A device for injecting electric charge into fluids consists of a p-n junction diode having the junctions so positioned that an active region of the semi-conductor is in contact with the fluid. A reverse electric field of a magnitude sufficient to release charge carriers having energies greater than the potential barrier at the surface of the semi-conductor is applied to the junction so that charge carriers are emitted from the active region. An electrode is also immersed in the fluid to enable a drift field to be established to attract charge carriers in the fluid away from the surface of the semi-conductor.
