Abstract In this paper we discuss interplays between the Aharonov-Bohm effect and the transport properties in mesoscopic ring structures based on graphene. The interlayer interaction leads to a change of the electronic structure of bilayer graphene ring such that the electronic energy dispersion law exhibits a gap, either by doping one of the layers or by the application of an external perpendicular electric field. Gap adjustments can be done by varying the external electric field, which provides the possibility of obtaining mesoscopic devices based on the electronic properties of bilayer graphene. This opens the way to controllable manipulations of phase-coherent mesoscopic phenomena, as well as to Aharonov-Bohm oscillations depending on the height of the potential step and on the radius of the ring. For this purpose one resorts to a tight-binding model such as used to the description of conductance.

Graphene field-effect transistors (GFETs) exhibit unique switch and sensing features. In this article, GFETs are investigated within the tight-binding formalism, including quantum capacitance correction, where the graphene ribbons with reconstructed armchair edges are mapped into a set of independent dual channels through a unitary transformation. A new transfer matrix method is further developed to analyze the electron transport in each dual channel under a back gate voltage, while the electronic density of states of graphene ribbons with transversal dislocations are calculated using the retarded Green’s function and a novel real-space renormalization method. The Landauer electrical conductance obtained from these transfer matrices was confirmed by the Kubo–Greenwood formula, and the numerical results for the limiting cases were verified on the basis of analytical results. Finally, the size- and gate-voltage-dependent source-drain currents in GFETs are calculated, whose results are compared with the experimental data.

In this paper, we investigate the aspects of electron transport in the zigzag graphene nanoribbons (ZGNRs) using the nonequilibrium Green’s function (NEGF) formalism. The latter is an esoteric tool in mesoscopic physics. It is used to perform an analysis of ZGNRs by considering potential well. Within this potential, the dependence of transmission coefficient, local density of states (LDOS) and electron transport properties on number of atoms per unit cell is discussed. It is observed that there is an increment in electron and thermal conductance with increasing number of atoms. In addition to these properties, the dependence of same is also studied in figure of merit. The results infer that the contribution of electrons to enhance the figure of merit is important above the crossover temperature.

We investigate the spin Hall effect in a single-layer graphene device with disorder and interface-induced spin–orbit coupling. Our graphene device is connected to four semi-infinite leads that are embedded in a Landauer–Büttiker setup for quantum transport. We show that the spin Hall angle of graphene devices exhibits mesoscopic fluctuations that are similar to metal devices. Furthermore, the product between the maximum spin Hall angle deviation and dimensionless longitudinal conductivity follows a universal relationship [Formula: see text]. Finally, we compare the universal relation with recent experimental data and numerically exact real-space simulations from the tight-binding model.

Using KITE [1], a quantum transport software developed by ourselves, we explore the effect of disorder in the second-order con¬ductivity, aiming to reproduce mesoscopic samples under more realistic models of disorder. This work will be concerned about our most recent results with KITE. We will showcase and examine how different mod¬els of disorder affect the same system, experimenting with Anderson disorder and vacancies in gapped Graphene.

When we talk about nano devices, the molecule and its interface with electrodes play a key role. So, one of the major objectives is to select an organic nanomaterial with extensive applications, which requires smart synthesis of appropriate materials and an understanding of their properties. Here we modeled a device, which not only adds another “protuberance” to learn about the transport properties of the molecule but also helps in grasping its use as a considerable material for future flexible electronics. Modeling of materials at the nano-level not only provides fundamental insight into the properties of crystalline defects but also gives a reasonable understanding of phase stability and learning of processes like atomic diffusion interface migration. For the development of devices at a mesoscopic and macroscopic level and with atomistic input parameters, this recognition serves as a guide. We tried to model how the layers of one type of molecule and the interaction of two different types of molecular layers control the junction charge transport characteristics.

Recently, fractional quantization of two-terminal conductance was reported in suspended graphene. The quantization, which was clearly visible in fields as low as 2 T and persistent up to 20 K in 12 T, was attributed to the formation of an incompressible fractional quantum Hall state. Here, we argue that the failure of earlier experiments to detect the integer and fractional quantum Hall effect with a Hall-bar lead geometry is a consequence of the invasive character of voltage probes in mesoscopic samples, which are easily shorted out owing to the formation of hot spots near the edges of the sample. This conclusion is supported by a detailed comparison with a solvable transport model. We also consider, and rule out, an alternative interpretation of the quantization in terms of the formation of a p–n–p junction, which could result from contact doping or density inhomogeneity. Finally, we discuss the estimate of the quasi-particle gap of the quantum Hall state. The gap value, obtained from the transport data using a conformal mapping technique, is considerably larger than in GaAs-based two-dimensional electron systems, reflecting the stronger Coulomb interactions in graphene.
