Vacuum micro/nano electronic devices possess merits of radiation hardness, temperature tolerance, high working frequency and output power. It's regarded as the promising candidates for the application on ultra-high speed transistor [1, 2], portable and fast-switch X-ray source [3], free electron laser [4], field emission display [5] and so on. In the developing of modern vacuum electronic, to achieve...
We report on an extended use of the Fowler-Nordheim plot for energetic evaluation of charge transfers in vacuum electronics. First results explained clearly, the transition from field electron emission to plasma discharge is physically conditioned, especially in the case of higher emission currents.
Strong electric fields are known to create biased adatom migration on metallic surfaces. We present a Kinetic Monte Carlo model that can simulate adatom migration on a tungsten (W) surface in electric fields. We validate our model by using it to calculate the drift velocity of the adatom at different fields and temperature and comparing the results with experimental data from the literature. We obtain...
