Predictive models

Computational 3D simulations of individual carbon nanotubes (CNTs) and vertically aligned arrays of CNTs were conducted in order to gain insight into their field emission characteristics. We find that the widely used approximation that the enhancement factor is equal to the aspect ratio of the emitter to be an over-estimation, and that the enhancement factor is only loosely related to the aspect ratio, among other parameters.
