Abstract
An electron emission source includes a first electrode, a semiconductor layer, an insulating layer, and a second electrode stacked in that sequence, wherein an electron collection layer is sandwiched between the semiconductor layer and the insulating layer, the electron collection layer is in contact with the semiconductor layer and the insulating layer, and the electron collection layer is a conductive layer to collect electrons.
Claims15
An electron emission source, the electron emission source comprising:
- a first electrode;
- a semiconductor layer on the first electrode and electrically connected to the first electrode;
- an insulating layer located on the semiconductor layer;
- and a second electrode located on a surface of the the insulating layer away from the semiconductor layer;
- wherein an electron collection layer is sandwiched between the semiconductor layer and the insulating layer, and the electron collection layer is a conductive layer to collect electrons.
