Abstract

We have calculated the lateral distribution of field emitted electrons from a CNF array - a quantity of importance in designing field emission displays - by calculating the electron distribution from an individual CNF and subsequently summing the contribution from all CNFs. We have not obtained the absolute current value but only the relative distribution in space. Its variation has been examined with respect to the following parameters: a) the CNF tip radius - R, b) the anode to cathode distance - d and c) the cathode to anode potential difference - . Reasonable agreement with experimental results is obtained.
