Drift velocity peak and negative differential mobility in high field transport in graphene nanoribbons explained by numerical simulations
Alessandro Betti, Gianluca Fiori, Giuseppe Iannaccone
We present numerical simulations of high field transport in both suspended and deposited armchair graphene nanoribbon (A-GNR) on HfO2 substrate. Drift velocity in suspended GNR doe…
Strong mobility degradation in ideal graphene nanoribbons due to phonon scattering
Alessandro Betti, Gianluca Fiori, Giuseppe Iannaccone
We investigate the low-field phonon-limited mobility in armchair graphene nanoribbons (GNRs) using full-band electron and phonon dispersion relations. We show that lateral confinem…
Atomistic investigation of low-field mobility in graphene nanoribbons
Alessandro Betti, Gianluca Fiori, Giuseppe Iannaccone
We have investigated the main scattering mechanisms affecting mobility in graphene nanoribbons using detailed atomistic simulations. We have considered carrier scattering due to ac…
Simulation of hydrogenated graphene Field-Effect Transistors through a multiscale approach
Gianluca Fiori, S. Lebègue, A. Betti +4
In this work, we present a performance analysis of Field Effect Transistors based on recently fabricated 100% hydrogenated graphene (the so-called graphane) and theoretically predi…
Enhanced shot noise in carbon nanotube field-effect transistors
Alessandro Betti, Gianluca Fiori, Giuseppe Iannaccone
We predict shot noise enhancement in defect-free carbon nanotube field-effect transistors through a numerical investigation based on the self-consistent solution of the Poisson and…
Statistical theory of shot noise in quasi-1D Field Effect Transistors in the presence of electron-electron interaction
Alessandro Betti, Gianluca Fiori, Giuseppe Iannaccone
We present an expression for the shot noise power spectral density in quasi-one dimensional conductors electrostatically controlled by a gate electrode, that includes the effects o…
