摘要:
The present disclosure is directed to an electron source and an X-ray source using the same. The electron source of the present invention comprises: at least two electron emission zones, each of which comprises a plurality of micro electron emission units, wherein the micro electron emission unit comprises: a base layer, an insulating layer on the base layer, a grid layer on the insulating layer, an opening in the grid layer, and an electron emitter that is fixed at the base layer and corresponds to a position of the opening, wherein the micro electron emission units in the same electron emission zone are electrically connected and simultaneously emit electrons or do not emit electrons at the same time, and wherein different electron emission zones are electrically partitioned.
摘要:
An electron emitting device includes a substrate, a plurality of first wiring units, each of the plurality of first wiring units including a plurality of first electrodes extending in a first direction on the substrate and spaced apart from each other, a plurality of second wiring units, each of the plurality of second wiring units including a plurality of second electrodes each extending in a direction substantially opposite to the first direction and interposed between adjacent first electrodes of the plurality of first electrodes, and a plurality of first electron emitters at sides of the first electrodes and a plurality of second electron emitters at sides of the second electrodes, wherein at least one of the plurality of first wiring units or the plurality of second wiring units is configured to be driven separately.
摘要:
Electron emission devices include first electrodes (22) on a substrate (12) extending in a first direction and spaced apart from each other. Second electrodes (24) are on the substrate alternating between the first electrodes and extending in a second direction opposing the first direction. First electron emitters (26) and second electron emitters (38) are on side surfaces of the first electrodes and the second electrodes, respectively. Gaps are formed between the first electron emitters and second electron emitters.
