Three-dimensional calculation of field emission from carbon nanotubes using a transfermatrix methodology

Abstract: We present simulations of field emission from carbon nanotubes, using a transfer-matrix methodology. By repeating periodically a basic unit of the nanotubes in the region preceding that containing the extraction field, specific band-structure effects are included in the distribution of incident states, i.e. those entering the field region. The structures considered are the metallic (5,5) and the semiconducting (10,0) single-wall carbon nanotubes. The total-energy distributions of incident states show the gap o… Show more

“…Recently, new techniques for self-aligned or patterned CNT film preparation on various supports 1-6 opened the way for the fabrication of a wide range of microelectronic devices. 9,12,13 While very important for single tube field emission, the contribution of such localized states may be wiped out when measuring the field emission current from a large CNT film, containing usually a broad mixture of different CNT symmetries and diameters. [9][10][11][12][13] Some of the present theoretical research concentrates mainly on the numerical analysis of the field emission from localized states on the CNT tip.…”
