在过去几年中,已经研制出多种不同的冷阴极结构,但结果都不太成功。效率低、寿命短,并且这些阴极的制作重复性很差。但是,在 Stanford 研究所的 D.V.Geppert 和 B.V.Dore 现研制了一种新型的冷阴极,该阴极连续工作了6000多小时尚未发现显著变坏。他们将这种阴极称为横向场发射体(或 TFE)。一些有希望的试验结果是:电子流进入 In the past few years, many different cold cathode structures have been developed, but the results have not been very successful. Inefficient, short life, and poor reproducibility of these cathodes. However, D.V. Gpertpert and B.V. Dore of the Stanford Institute have now developed a new type of cold cathode that has not found significant deterioration for more than 6000 hours of continuous operation. They call this cathode a lateral field emitter (or TFE). Some promising test results are: Electron flow into
