Coherent quantum transport features in carbon superlattice structures

Whilst resonant transmission is well understood and can be fully harnessed for crystalline superlattices, a complete picture has not yet emerged for disordered superlattices. It has proven difficult to tune resonant transmission in disordered diamond-like carbon (DLC) superlattices as conventional models are not equipped to incorporate significant structural disorder. In this work, we present c...

Quantum confinement phenomena in nanowire superlattice structures

Nanowire superlattices (NWSLs) are objects with a wide range of potential applications in nanoscale electronics and photonics. These objects are already grown experimentally in laboratories and studies of their properties represent an important task in nanotechnology research. Tools of mathematical modelling provide a powerful means for studying these fascinating structures with an ultimate goa...

Terahertz electroluminescence from superlattice quantum cascade structures

Intersubband electroluminescence is reported in a quantum-cascade structure based on asymmetric superlattice active regions and designed for emission in the THz range ~l'80 mm!. Comparison with a structure based on a ‘‘vertical transition’’ in a single quantum well shows an increased full width at half maximum ~2.8 vs 0.9 meV! of the emission line. In both cases the dependence of the optical po...

Coherent Transport of Single Photon in a Quantum Super-cavity with Mirrors Composed of Λ-Type Three-level Atomic Ensembles

In this paper, we study the coherent transport of single photon in a coupled resonator waveguide (CRW) where two threelevel Λ-type atomic ensembles are embedded in two separate cavities. We show that it is possible to control the photon transmission and reflection coefficients by using classical control fields. In particular, we find that the total photon transmission and reflection are achieva...

Quantum transport in carbon nanotubes

In the last twenty years, due to technological advances, it has become possible to build, manipulate and observe nanometer structures and so their dimensions are intermediate between the microscopic and macroscopic. These new systems present novel features and have originated the new field of mesoscopic physics As for the transport properties the mesoscopic conductors do not have ohmic behaviou...
