Evidence for Non-existence of Oscillations in Photofield Emission Current in Gallium Arsenide

We have shown here the results of PFEC(photofield emission current)calculated for GaAs(gallium arsenide).We have used the initial state wavefunctions derived using the Kronig-Penney potential model for evaluating the PFEC.We have found that PFEC is not oscillatory as obtained by Modinos and Klient,[Solid State Commun.50,651(1984)],but it is an exponential function.

高温超导体光场发射研究

】在低于场致发射电场阈值的场强作用下，发射体受脉冲激光照射时将会产生光场发射。文中对高温超导体临界温度以上光场发射电流做了一定的研究，并与一般的场致发射电流做了一些比较。

大电流金属光-场发射的计算

在低于场致发射电场阈值的场强下,冷阴极受到脉冲激光照射将产生光一场发射。对金取光-场发射的半经典计算结果表明,光-场发射较场发射更适于产生短脉宽高亮度电子束,且比普通光电发射具有更高的量子产额。文中特别对大电流工作特性进行了讨论。
