Within the non-equilibrium Green's function formalism numerical integration plays an important role. Several adaptive integration methods were realized and compared regarding convergency within a self-consistent Schrödinger-Poisson loop, computation time and memory consumption.

Vertically grown carbon nanotubes have the potential for tera-level Integration. However, the well-known ambipolar behavior limits the performance of carbon nanotube field effect transistors. In this work we demonstrate that a double gate structure effectively [...]
