Abstract:

The possibility of using the two-band superconductor model1 by taking into consideration the electron scattering at the lattice defects and the correlation interaction of the wide- and narrow-band electrons for describing the kinetic properties of high-Tc superconductors (HTS) in normal state is discussed. Specific features of the relaxation processes in the electron system of a narrow-band conductor, viz. the non-Born impurity scattering in the region of band overlapping, and an anomalous increase in the electron–electron scattering for a partially filled narrow band, are explained. The temperature dependence of resistance, caused by the interference of various relaxation mechanisms, contains a broad-linear region typical of HTS, while the thermoelectric coefficient has an anomalously large value which reverses its sign upon a variation of temperature and electron concentration. A comparison is made between the kinetic and thermodynamic properties of the two-band model for different values of its microscopic parameters.

Abstract:

Reduction in threshold current density is the major challenge in the field of semiconductor laser design. The threshold current density can be minimized by introducing low dimensional material system with narrow band gap. InN has a narrow band gap of 0.7 eV and quantum dot provides three dimensional confinement factor. In this paper, we propose then InN quantum dot as the active layer material that will serve both the purpose of narrow band gap and three dimensional confinement. The simulation results show that the current density reduces drastically with the cavity length.

Abstract:

In recent years, research of the narrow-band-gap polymer photovoltaic (PV) materials in the field of light-emitting diodes, field effect transistors, solar cells and sensors has made tremendous progress and its application becomes more widely. In order to obtain a better performance of the photovoltaic material, in the process of design the polymer, we must consider the spectral range, the energy gap, the balance between the LUMO and HOMO level. Through the analysis of the narrow-band-gap polymers, this paper described the synthesis of the photovoltaic material, and detailed analyzes its photovoltaic characteristics. This paper introduces the double bonds to combine DTBT receptors and different electron donor, to synthesize new narrow-band-gap polymer photovoltaic materials with photovoltaic properties.

Abstract:

We investigate the band structure of narrow armchair-edge graphene nanoribbons (AGNRs) under tensile strain by means of an extension of the Extended Hückel method. The strain-induced band gap modulation presents asymmetric behavior. The asymmetric modulation of band gap is derived from the different changes of conduction and valence bands near Fermi level under tensile strain. Further analysis suggests that the asymmetric variation of band structure near Fermi level only appear in narrow armchair-edge graphene nanoribbons.

Abstract:

Infrared optoelectronics is driven by epitaxially grown semiconductors and the introduction of alternative materials is often viewed with some suspicion until the newcomer has demonstrated a high degree of viability. Infrared nanocrystals have certainly reached this degree of maturity switching from the demonstration of absorption by chemists to their integration into increasingly complex systems. Here, we review some of the recent developments relative to the integration of nanocrystal devices in the 1-5 µm range.

Abstract:

In this work we are concerned with magnetic junction structures in which a homogeneous narrow-gap semiconductor is subjected to an inhomogeneous magnetic field, in an attempt to elucidate the band-structure effect on the resonance tunneling. Careful investigation of the transmission as a function of the energy shows that the resonances in the spectrum can appear. These are remnants of the Landau levels localized near the interface boundary. Comparing the solutions obtained within two-band and single-band models we found the allowed values of the momentum to be quite different, resulting in different resonant values of the transmission coefficient of electron transport through the magnetic interface.

Abstract:

The band gap of 2D perfect phononic crystal thin plate was investigated by plane-wave expansion (PWE), which is consist of copper embedded in the organic glass with a square arrangement. The band gap of straight linear defect, branching linear defect, and symmetrical linear defect are calculated by supercell plane wave method respectively. It is found that the bandwidth of defect structure will become narrow. Especially there is little band gap appearing for straight linear defect. As the filling fraction varied, the band gap width and the band gap number changed.

Full text

Abstract:

Influence of parameters of a quantum well and electronic polarizability spatial dispersion on the dependence of two-dimensional plasmon energy on wave vector in narrow-gap CdHgTe quantum wells (band gap 35 meV) is studied theoretically. It is shown that at energies above 20 meV, the dispersion law of two-dimensional plasmons is close to linear. Taking into account the finite width of the quantum well decreases the plasmon phase velocity. This effect increases with an increase in the fraction of cadmium in the QW while maintaining the band gap and with a decrease in the concentration of charge carriers in it. Keywords: two-dimensional plasmon, narrow-gap HgTe.

Abstract:

TiO2 thin film has become a widely used photocatalyst due to its stable chemical properties, suitable edge position, non-toxicity and low cost, and the film structure is conducive to recycling and loading. However, because the band gap of titanium dioxide is relatively wide, visible light is difficult to be utilized, which also limit the utilization of TiO2. In recent years, non-metallic doping has been proven to be an extraordinarily efficient methodologies to reduce band gap and improve photocatalytic efficiency of TiO2 films. In this paper, the basic principle of photocatalysis and the principle of reducing band gap by doping inorganic non-metallic elements are briefly introduced, and the preparation methods of N, C and B inorganic non-metallic elements doped TiO2 films are reviewed, as well as their functions on reducing band gap of TiO2. Finally, the research status of inorganic non-metallic element doped TiO2 thin film in photodecomposition of water and organic decomposition in catalytic solution was introduced.
