Mathematical Simulation of Emission Devices on Arrays of Carbon Nanotubes

With the help of the described approaches to electric field (EF) modelling in the systems with carbon nanotubes (CNTs) arrays, analysis of such arrays parameters influence on the degree of the EF strength amplification on CNTs tips have been performed. Such approaches enable EF calculation at the applied computational grid step proportional to the CNTs height and for only one CNT from the array. Influence of correlation between the CNTs height, radius and distance between separate rods on the character of the EF distributions has been evaluated.
