Abstract: An electron emitting device includes a first electrode located on a substrate (1), an insulating layer located on the first electrode (2), and a second electrode (3) located on the insulating layer. Various examples are described. In one example, the second electrode has a first surface and a second surface, which are substantially vertical to a direction that the first electrode and the insulating layer are laminated. The first surface of the second electrode is in contact with the insulating layer. A higher potential than that applied to the second electrode is applied to the first electrode to emit an electron from the second surface.

Abstract: PROBLEM TO BE SOLVED: To provide an electrodeposition controlling method for monitoring the position at the objective place and stopping electrodeposition. SOLUTION: The electrode 1 to be electrodeposited, a counter electrode 2 and a reference electrode 3 are connected to a potentiostat 4, and a monitor electrode 5 is connected to a power source 7 via an ammeter or a voltmeter 6. Electrodeposition is executed in such a manner that the potential of the monitor electrode 5 viewed from the reference electrode 3 is set to be baser than the oxidation-reduction potential and nobler than the electrode 1 to be electrodeposited, and at the instant in which an electrodeposit 13 comes into contact with the monitor electrode 5, a measuring instrument 6 detects the change of the electric current value or voltage caused by the potential difference between the electrode 1 to be electrodeposited and the monitor electrode 5, a personal computer 9 allows the potentiostat 4 and the power source 7 to stop the potential feed, and the electrodeposition is stopped.
