Abstract
In recent density-functional-theory (DFT) calculations on small single-walled carbon nanotubes, it has been found that subtracting-off the zero-field components to form induced charge, potential, field and field-enhancement-factor distributions leads to useful theoretical insights and better consistency with the best experiments. This Poster represents an interim report that summarizes the current state of our thinking, and indicates the issues that we consider need to be explored further.
