Thermal conductivity reduction in rough silicon nanomembranes
Giovanni Pennelli, Elisabetta Dimaggio, Massimo Macucci
Nanostructured silicon is a promising material for thermoelectric conversion, because the thermal conductivity in silicon nanostructures can be strongly reduced with respect to tha…
High-performance solution of the transport problem in a graphene armchair structure with a generic potential
Demetrio Logoteta, Paolo Marconcini, Claudio Bonati +2
We propose an efficient numerical method to study the transport properties of armchair graphene ribbons in the presence of a generic external potential. The method is based on a co…
Symmetry-dependent transport behavior of graphene double dots
Paolo Marconcini, Massimo Macucci
By means of an envelope function analysis, we perform a numerical investigation of the conductance behavior of a graphene structure consisting of two regions (dots) connected to th…
Sinc-based method for an efficient solution in the direct space of quantum wave equations with periodic boundary conditions
Paolo Marconcini, Demetrio Logoteta, Massimo Macucci
The solution of differential problems, and in particular of quantum wave equations, can in general be performed both in the direct and in the reciprocal space. However, to achieve…
Atomistic Boron-Doped Graphene Field Effect Transistors: A Route towards Unipolar Characteristics
Paolo Marconcini, Alessandro Cresti, Francois Triozon +5
We report fully quantum simulations of realistic models of boron-doped graphene-based field effect transistors, including atomistic details based on DFT calculations. We show that…
Is the regime with shot noise suppression by a factor 1/3 achievable in semiconductor devices with mesoscopic dimensions?
Paolo Marconcini, Massimo Macucci, Demetrio Logoteta +1
We discuss the possibility of diffusive conduction and thus of suppression of shot noise by a factor 1/3 in mesoscopic semiconductor devices with two-dimensional and one-dimensiona…
