Engineering the electromagnetic environment in a nanostructure to study single electron tunneling

The application of nanopatterned electrode materials is a promising method to improve the performance thin-film optoelectronic devices such as organic light-emitting diodes (OLEDs) and photovoltaics. Light coupling active layers enhanced by employing nanopatterns specifically tailored device structure. A range different typically evaluated during development process. Fabrication each these usin...

tellurium (te) nanostructures have been successfully synthesized via a simple hydrothermal methodfrom the reaction of a tecl4 aqueous solution with thioglycolic acid (tga) as a reductant. tga can be easily oxidized to the corresponding disulfide [sch2co2h]2, which in turn can reduce tecl4 to te. the obtained te was characterized by xrd, sem, eds, and drs. the effect of reducing agent on morphol...

transparent glasses in a system of li2o-mgo-sio2-al2o3-fchemical constituents were prepared by melt quenching method. in the fabrication of nanocrystal glass-ceramics, controlled nucleation and subsequent crystal growth were necessary to avoid loss of transparency. it was therefore important to understand thermal properties and crystallization kinetics of the glass ceramics. the crystallization...

in this paper, the accumulative channel-die compression bounding (accb) method is investigated as a new method of severe plastic deformation to produce nano-crystalline bulk metals on the basis of pressing in a channel mold. aluminum as one of the most usable metal in industry is processed using this method. analyzing the processed samples show that after four passes of accb method, the ultimat...

The paper presents the wave functions ψ, probability functions ψψ* and the ground states energy of a nanostructure consisting of a Si QD embedded in SiO2 dielectric medium, which is under bias of varying electrostatic field. Abrupt displacement of the peak of ψψ* at a certain field value is elucidated as the QD emission. The field distribution and the characteristics of the nanostructure quantu...

We report on the synthesis, morphology, chemically and structurally of TiO2-NiO-SiO2 nanostructure. The TiO2-NiO-SiO2 nanostructure was synthesized by a method based on the sol-gel method, by the simultaneous gelation of all cations. The coatings were deposited on dried soda-lime glass slides by spin coating. Composite powders and coating on glass hav...

optical modeling was applied for obtaining absorbance spectra and band gap values for different morphology of zno semiconductor. in optical modeling, the relative permittivity scalars of zinc oxide coral like nanorods were calculated using the bruggeman homogenization formalism. zno nano rods (zonrs) as a nucleus layer were fabricated on the indium tin oxide (ito) by chronoamperometry (ca) in a...

the preparation of nanostructure type manganese oxide and cobalt oxide materials with the smallest particle size is reported here. the nanorod manganese oxide and cobalt oxide nanotube were prepared via a sol-gel reaction in reverse micelles from kmno4 and cocl2 with respectively source at room-temperature. the structure and surface morphology of the obtained manganese oxide were studied by mea...
