The talk will mainly concentrate on the results of optical and morphological properties of zinc oxide (ZnO) nanostructures and on some recent work on organic polymer based photovoltaic devices. Low dimensional nanostructures of ZnO have potential to improve the efficiency and compactness of electronic and photonic devices including LEDs, optical waveguides and sensors. The growth mechanism and ...

BACKGROUND Semiconductor doped nanostructure materials have attained considerable attention owing to their electronic, opto-electronic, para-magnetic, photo-catalysis, electro-chemical, mechanical behaviors and their potential applications in different research areas. Doped nanomaterials might be a promising owing to their high-specific surface-area, low-resistances, high-catalytic activity, at...

Unlike the electrical conductance that can be widely modulated within same material even in deep nanoscale devices, tuning thermal a single system or nanostructure is extremely challenging and requires large-scale device. This prohibits realization of robust ON/OFF states switching flow currents. Here, we present theory switch based on resonant coupling three photonic resonators, analogy to fie...

A complex three-dimensional (3D) feather-like AlN nanostructure was synthesized by a direct reaction of high-purity Al granules with nitrogen using an arc discharge method. By adjusting the discharge time, a coral-like nanostructure, which evolved from the feather-like nanostructure, has also been observed. The novel 3D feather-like AlN nanostructure has a hierarchical dendritic structure, whic...

We demonstrate through simulations the feasibility of using magnetically coupled nanometer-scale ferromagnetic dots for digital information processing. Microelectronic circuits provide the input and output of the magnetic nanostructure, but the signal is processed via magnetic dot–dot interactions. Logic functions can be defined by the proper placements of dots. We introduce a SPICE macromodel ...

The chemical composition, nanostructure and electronic structure of nanosized oxide scales naturally formed on the surface of AISI 316L stainless steel microfibres used for strengthening of composite materials have been characterised using a combination of scanning and transmission electron microscopy with energy-dispersive X-ray, electron energy loss and Auger spectroscopy. The analysis reveal...
