The transport properties of Dirac fermions through armchair-edge graphene nanoribbons (AGNRs) with a single and double rectangular Fermi velocity v F and electrostatic potential U barriers is investigated. We employ a transfer matrix method (TMM) to

Code smells typically indicate poor design implementation and choices that may degrade software quality. Hence, they need to be carefully detected to avoid such poor design. In this context, some studies try to understand the impact of code smells on

Context: During software development, developers can make assumptions that guide their development practices to avoid bug-introducing changes. For instance, developers may consider that code with low test coverage is more likely to introduce bugs; an

The discrete nonlinear Schrodinger equation (DNSE) describes wave phenomena in several physical contexts, ranging from electronic transport in crystalline chains to light propagation in nonlinear media and Bose-Einstein condensates. Here, we study th

We study the one-electron wavepacket dynamics in a C 60 buckyball topology with a relaxing nonlinearity. The electron dynamics is considered to be governed by a discrete Schrodinger equation on which the nonlinear contribution obeys a Debye-like rela

In the present article, we study the spin-dependent thermoelectric properties of a quantum dot connected to two ferromagnetic contacts. We obtain results for the conductance, thermopower, thermal conductance, Lorentz ratio and figure of merit. The tr

We study the effects of exciton confinement on the nonlinear optical susceptibility of one-dimensional quantum dots. We use a direct numerical diagonalization to obtain the eigenenergies and eigenstates of the discretized Hamiltonian representing an

The morphological and wetting properties of chitosan films containing dansyl derivatives have been investigated. By means of dynamic contact angle measurements, we study the modification of surface properties of chitosan-based films due to UV irradia

The electronic states of a hydrogenic donor in two-dimensional quantum rings are calculated by taking into account the finite width of the potential well in the ring. In addition, a strong magnetic field is applied perpendicular to the quantum ring.
