CA 2507454

A comb-shaped electrode is formed on the main surface of a ferroelectric thin film and a planer electrode is formed on the rear surface of a ferroelectric thin film. Then, the property of the main surface of the ferroelectric thin film is converted into semi-conduction. Then, the assembly comprised of the ferroelectric thin film, the comb-shaped electrode and the planer electrode is disposed in a given atmosphere. Under the circumstance, a negative voltage is applied to the comb-shaped electrode to polarize the ferroelectric thin film, and a negative impulse voltage is applied to the planer electrode, thereby generating electron beams from the main surface of the ferroelectric thin film.
