摘要
采用微通道板测量阴极在高真空(1.3*10/sup -5/ Pa)高场和紫外照射范围(10/sup -19/ A ~ 10/sup -15/ A)下的发射电子。发现光电子主要从阴极表面的平坦部分发射。电子的数目在场发射的起始场强之下保持不变。场发射的起始场强与光子能量无关。光子能量对微小投影的电子发射的影响没有出现。
Property of electron emission under irradiation of ultraviolet ray and applying field
A microchannel plate was used to measure emitted electrons under high field and ultraviolet irradiation of a cathode within the range of 10/sup -19/ A to 10/sup -15/ A in high vacuum (1.3*10/sup -5/ Pa). It is found that photoelectrons are mainly emitted from a flat part of the cathode surface. The number of the electrons is kept constant below the inception field strength of the field emission. The inception field strength of the field emission does not depend on photon energy. The effect of the photon energy on the electron emission from the minute projections did not appear.<>
