This paper describes recent progress in large scale numerical simulations for computational nano-electronics using the NEMO3-D package. NEMO3-D is a parallel analysis tool for nano-electronic devices such as quantum dots. The atomistic model used in NEMO3-D leads to large scale computations in two main phases: strain and electronic structure. This...

... Fig. 4(a) and (b) the same kind of results are shown for a (25,0) CNT-FET. In this case, more modes (four modes) are needed in order to accurately reproduce the transfer character- istics provided by the real space approach, because of the larger diameter. When four modes are taken into account, the mode space is almost 20 faster than the real space approach. A safe approach to choose the number of considered modes for a given structure and bias is to perform multiple simulations with in- creasing number of modes, and then stop when adding more modes does not modify the obtained results in a significant ...
