The diverse applications of terahertz (THz) radiation and its importance to fundamental
science makes finding ways to generate, manipulate and detect THz radiation one of the key …

Terahertz (THz) technologies are promising for diverse areas such as medicine,
bioengineering, astronomy, environmental monitoring, and communications. However …

Plasmon resonance is expected to occur in metallic and doped semiconducting carbon
nanotubes in the terahertz frequency range, but its convincing identification has so far been …

The second-order nonlinear optical (NLO) processes, such as photogalvanic effect and
second-order harmonic generation (SHG), play crucial roles in probing and controlling light …

We analyze bound modes of two-dimensional massless Dirac fermions confined within a
hyperbolic secant potential, which provides a good fit for potential profiles of existing top …

In this work a new scheme is proposed to study the exact solutions of another class of
hyperbolic potentials U p. We first obtain two linearly dependent eigenfunctions …

In our work, we investigate characteristics of conductivity for single-walled carbon nanotubes
caused by spin–orbit interaction. In the case study of chirality indexes, we especially …

We present an analytical tight-binding theory of the optical properties of graphene
nanoribbons with zigzag edges. Applying the transfer matrix technique to the nearest …

We obtain exact solutions to the two-dimensional (2D) Dirac equation for the one-
dimensional Pöschl-Teller potential which contains an asymmetry term. The eigenfunctions …

Single-wall carbon nanotubes provide ideal model one-dimensional (1-D) condensed
matter systems in which to address fundamental questions in many-body physics, while, at …
