Japanese Patent JP2603233
Kind Code:
B2
Abstract:
PURPOSE:To realize a compact optical switching electron emitting element by integrally laminating and constituting a junction type optoelectric transducer performing optoelectric-converting incident beams, and an electron emitting element emitting electrons in response to output currents from the transducer. CONSTITUTION:A P-I-N photodiode is organized of a p<+> layer 1, an i layer 2 and an n<+> layer 3, while an electron emitting element is laminated integrally onto the P-I-N photodiode. The electron emitting element is organized of a conductive layer 4, an insulating layer 5 and a metallic layer 6. When reverse bias voltage VR is applied between the p<+> layer 1 and the n<+> layer 3 and voltage V is applied between the conductive layer 4 and the metallic layer 6 in an optical switching electron emitting element constructed in this manner, carrier electrons generated by optical absorption are injected to the conductive layer 4, and the injected electrons are accelerated in speed, and emitted from the metallic layer 6.
