SURFACE EMISSION TYPE ELECTRON SOURCE AND DRAWING DEVICE

摘要

A surface emission type electron source comprises a planar first electrode, a planar second electrode provided in opposition to the first electrode, an electron passage layer provided between the first electrode and the second electrode, and a power section for applying voltage to the second electrode and the first electrode. In the electron passage layer, a plurality of quantum wires extending in a first direction heading for the second electrode from the first electrode are provided with a predetermined gap therebetween. Electrons are emitted from the surface of the second electrode. The quantum wire is composed of silicon. In the quantum wire, a plurality of portions whose thickness is thin are formed with a predetermined gap therebetween in the first direction.
