We predict the possibility of shot noise enhancement in defect-free Carbon Nanotube Field Effect Transistors, through a numerical investigation based on Monte Carlo simulations of randomly injected electrons from the reservoirs and the self-consistent solution of the Poisson and Schrodinger equations within the non-equilibrium Green's functions formalism. Such enhancement can be explained by a positive...
We discuss an intriguing set of transport and noise properties of graphene-based transistors that can be investigated in a direct way with atomistic modeling - Non-Equilibrium Green's Functions with a Tight-Binding Hamiltonian - and are not directly accessible with models based on a higher level of physical abstraction. We present an investigation of the achievable electron mobility in channels based...
We present a novel method for the evaluation of shot noise in quasi-1-D field-effect transistors, such as those based on carbon nanotubes and silicon nanowires. The method is derived by using a statistical approach within the second quantization formalism and allows the inclusion of both the effects of Pauli exclusion and Coulomb repulsion among charge carriers. This way, it extends the Landauer-Buttiker...
