Molecular dynamics simulations, with full Coulomb interaction and self-consistent field emission, are used to examine mutual space–charge interactions between beams originating from several emitter areas, in a planar infinite diode. The simulations allow observation of the trajectory of each individual electron through the diode gap. Results show that when the center-to-center spacing between emitters is greater than half of the gap spacing the emitters are essentially independent. For smaller spacing the mutual space–charge effect increases rapidly and should not be discounted. A simple qualitative explanation for this effect is given.

平面场发射体间互空间电荷效应的分子动力学模拟

分子动力学模拟具有完整的库仑相互作用和自洽场发射，用于检查平面无限二极管中源自多个发射区的光束之间的相互空间电荷相互作用。模拟允许观察每个单独电子通过二极管间隙的轨迹。结果表明，当发射器之间的中心间距大于间隙间距的一半时，发射器基本上是独立的。对于较小的间距，相互空间电荷效应迅速增加，不应忽视。对这种效应给出了一个简单的定性解释。
