Recently, a lot of interest has been generated in the area of Macroelectronics with applications such as displays, chemical/biological sensors, photovoltaics and power electronics. Nanobundle network transistors (NBTs) have emerged as a viable, higher performance alternative to poly-silicon and organic transistors for these applications. Several experimental groups are coming up with a lot of experimental data but there is no theoretical model to explain these recent experiments. <br> <br>In the paper we develop the analytical models for the NBTs with channel length less that the tube length (for sub-percolating networks) and use it to explain some of the recent findings in the experiments by Infineon Technology. We also develop a numerical model for transistors with channel length greater than tube length based on percolation theory solving Poisson and Drift diffusion equation self consistently.
