    • A method for operating a charged particle beam emitting device and, in particular, an electron beam emitting device including a cold field emitter is provided. The method includes the steps of placing the cold field emitter in a vacuum of a given pressure, the emitter exhibiting a high initial emission current I0 and a lower stable mean emission current IS under a given electric extraction field; applying the given electric extraction field to the emitter for emitting electrons from the emitter surface; performing a cleaning process by applying at least one heating pulse to the cold field emitter for heating the emitter surface, whereby the cleaning process is performed before the emission current of the cold field emitter has declined to the lower stable mean emission value IS; and repeating the cleaning process to keep the emission current of the emitter continuously above the substantially stable emission value IS.

    • The invention provides an electron beam device 1 comprising at least one field emission cathode 3 and at least one extracting electrode 5, whereby the field emission cathode 5 comprises a p-type semiconductor region 7 connected to an emitter tip 9 made of a semiconductor material, an n-type semiconductor region 11 forming a pn-diode junction 13 with the p-type semiconductor region 7 a first electric contact 15 on the p-type semiconductor region 7 and a second electric contact 17 on the n-type semiconductor region 11. The p-type semiconductor region 7 prevents the flux of free electrons to the emitter unless electrons are injected into the p-type semiconductor region 7 by the pn-diode junction 13. This way, the field emission cathode 3 can generate an electron beam where the electron beam current is controlled by the forward biasing second voltage V2 across the pn-diode junction. Such electron beam current has an improved current value stability. In addition the electron beam current does not have to be stabilized anymore by adjusting, the voltage between emitter tip 9 and extracting electrode 5 which would interfere with the electric field of electron beam optics. The present invention further provides the field emission cathode as described above and an array of field emission cathodes. The invention further provides a method to generate at least one electron beam.
    • 本发明提供一种包括至少一个场发射阴极3和至少一个提取电极5的电子束装置1,由此场发射阴极5包括连接到由半导体材料制成的发射极尖端9的p型半导体区域7, 在p型半导体区域7上形成p型二极管结13的n型半导体区域11,p型半导体区域7上的第一电接触15和n型半导体区域11上的第二电接触17。 p型半导体区域7防止自由电子束流到发射极,除非电子被pn二极管结13注入到p型半导体区域7中。这样,场发射阴极3可以产生电子束,其中 电子束电流由跨越pn二极管结的正向偏置第二电压V 2控制。 这种电子束电流具有改善的电流值稳定性。 此外,电子束电流不必通过调节发射极尖端9和提取电极5之间的电压,这将干扰电子束光学器件的电场。 本发明还提供如上所述的场致发射阴极和场发射阴极阵列。 本发明还提供了一种产生至少一个电子束的方法。
