Numerical simulation of non-homogeneous 2D-CNT structures

A numerical model for inhomogeneous devices simulation as 2D-carbon nanotubes thin films is presented. This model takes into account nonlinear effects, in this work the proposed approach is based on tube-tube junctions which are presented as nonlinear dipoles depending on the nature of each junction (M/M), (SC/SC) and (M SC). Modified Nodal Analysis “MNA” and the adjoint network method are respectively used to simulate the current and the 1/f noise. This type of simulation allows understanding and analyzing of unexpected experimental results. In this paper simulation point-out the impact of nanotubes' clusters on the 1/f noise behavior of the NT films.
