“…The details are also available in other articles. [34][35][36][37] Although the theoretical formulation presented above is based on a general approach considering finite width leads having M number of channels, for completeness of the theoretical description, but in this article, we present all the numerical results (Sec. III) considering single-channel leads.…”

Within a tight-binding framework, we use a general spin density matrix formalism to evaluate all three components (P x , P y , and P z ) of the polarization vector associated with the charge current through the outgoing leads. It explores the dynamics of the spin polarization vector of current propagating through the system subjected to the Rashba and/or the Dresselhaus spin-orbit couplings. The sensitivity of the polarization components on the electrode-ring interface geometry is discussed in detail. Our present analysis provides an understanding of the coupled spin and electron transport in mesoscopic bridge systems. V C 2013 AIP Publishing LLC.

“…In recent years, the heat transfer property of carbon-nitride nanostructures with impurities, interfaces, and defects at the atomic scale has been studied [13][14][15]. A system containing periodic potential is called a superlattice, namely, a periodic structure composed of two or more materials [16,17].…”

Using the Tight Binding (TB) parameters extracted from Density Functional Theory (DFT) and Recursive Green's Function method (RGF), it is shown that skewed-zigzag black phosphorous (phosphorene) nanoribbons obtain large and tuneable bandgap in response to vertical and transverse electric fields. Depending on the direction of the applied field the mid-gap states could possess the localized or metallic nature i.e. non-zero mid-gap density of states. Adjustability of the bandgap and optical dipole transition matrix elements are explained based on the symmetry of involved band edge states. This promises new electronic and optical devices based on phosphorene nanoribbons.
