In this paper we analyze the effects of the hot phonon and self-heating on the static electronic transport characteristics of monolayer graphene. For this purpose, the Ensemble Monte Carlo method self-consistently coupled to a thermal resistive model for the heat dissipation is employed. This way, the most relevant mechanisms that limit the drift velocity are considered in a microscopic framework...
The small signal response and noise temperature in graphene under non-degenerated conditions is evaluated by means of a combined Monte Carlo-balance equations approach. The method correctly predicts the qualitative behavior of the most relevant quantities, such as real part of the differential mobility or diffusion coefficient, being much more computationally efficient that full ensemble Monte Carlo...
In this work, the influence of the underlying substrate on the mobility and electronic transport in graphene is evaluated by means of an ensemble Monte Carlo simulator. The substrates considered are h-BN, SiC, SiO2 and HfO2. The substrate type strongly affects the low-field mobility, particularly at room temperature; however, at low temperature the differences between supported graphene and suspended...
In this work, the instantaneous velocity and momentum fluctuations in suspended monolayer graphene are investigated by means of an ensemble Monte Carlo simulator. Due to the particular properties of graphene bandstructure (conical dispersion relationship near the Dirac points), instantaneous velocity fluctuations show a non-linear dependence with time during free flights, being limited by the maximum...
A microscopic study of electronic transport in suspended monolayer graphene is presented. The results have been obtained by means of an ensemble Monte Carlo simulator that takes into account the main physical properties of the graphene bandstructure and the most relevant scattering mechanisms for this type of material. The carrier velocity value is mainly set by the dominant influence of optical and...
