Simulation of thin film field emitter array cathodes

In typical field emitter arrays, individual gates have micrometer dimensions, whereas emitter tip radii are generally two orders of magnitude smaller. Because of this large size differential, it is necessary to use nonuniform meshes to accurately model such devices in a single computer run. This paper describes additions to the deformable triangular mesh finite element based beam optics code of the author, DEMEOS, which enable convenient simulation of field emitter array cathodes.<
