A novel nanowire hybrid structure for high-efficiency solar cells that axially connects nanowire core-shell p-n junctions is proposed and simulated. An efficiency of 16.8% is obtained at a filling ratio of 0.196.
GaAs/InGaAs/GaAs core-multishell nanowire heterostructure with a thin InGaAs quantum well is fabricated. Photoluminescence of the quantum well exhibits a blue shift along the nanowire due to the difference of diffusion length between In and Ga.
In this research, the interface between natural fibres and thermoplastic matrices is studied, in which fibre-matrix wetting analysis and interfacial adhesion are investigated to obtain a systematic understanding of the interface. In wetting analysis, the surface energies of the fibres and the matrices are estimated us…
Reversible cellular automata (RCAs) are a special class of cellular automata with some very distinctive properties. We present a novel observation regarding a certain class of RCAs, a class that includes Norman Margolus ’ “Critters ” rule. From a broad range of initial conditions, this class of cellular au-tomata conv…
In this paper, we present our strategies to use innovative photonic approaches to tackling the key challenges in transforming the nanophotonics solar cell concept to a viable high efficiency technology solution for the solar industry.
Plasmonic dye sensitized solar cells with three sorts of nanoparticles are investigated. By utilizing nanoparticles of different geometries and metals, optical and electrical improvement is demonstrated whilst the efficiency is significantly boosted over 30%.
A method for enhancement of color saturation and gamut in terms of excitation-purity and chromaticity coordinates in a CIE 1931 chromaticity diagram is presented for a dual-band color filter based on a rectangular metal-dielectric resonant-grating.
To achieve very high reflection over a wide bandwidth only for a chosen polarization, a circular Bragg grating mirror based on slotted waveguides is proposed and its technical feasibility was demonstrated using 3D FDTD simulations. © 2014 Engineers Australia.
The radiation-induced attenuation and the radiation sensitivity of a miniature gamma-ray dosimeter based on silica optical fiber incorporated with Co/Fe/Al metal particles were 3.77 dB and 0.003 dB/Gy with γ-ray irradiation dose-rate of 38.26 Gy/min, respectively.
Highly nonlinear CMOS-compatible hydrogenated amorphous silicon (a-Si:H) waveguides are studied for broad bandwidth and low-power parametric processing. Utilizing its favorable nonlinear properties, optical parametric amplification and oscillation are demonstrated.
Metamaterial wire media support sub-diffraction imaging, however images deteriorate near Fabry-Perot slab resonances. Using simple, local models, we show that image aberrations originate from cavity resonances in anisotropic media with large absolute axial permittivity.
In this work substantiated the necessity of regulation of burning process in the main combustion chamber of a gas turbine engine. Computational model of the main combustion chamber of a serial gas turbine engine was developed using the numerical simulation of three-dimensional thermo-gasdynamics modeling by the softwa…
Samples of as-extruded ZK60 magnesium alloy were subjected to 6 passes of equal-channel angular pressing (ECAP) following route A. The processing temperature was decreased with the number of passes. The structural evolution of the deformed samples was analyzed using Electron Backscattered Diffraction (EBSD) and X-Ray…
Graphene stickers are prepared by simple detaching the spin-coated polymer together with graphene directly grown on Al2O3 substrates. Nonlinear operation of the stickers is verified by realizing the saturable absorbers for laser short pulse formation.

Abstract—The solid state reaction method followed by the ball milling technique was used to synthesize the nano sized La0.72Sr0.28MnO3 (LSMO) perovskite samples with different grain
Protocellular boundaries were inextricably connected to the metabolism they encapsulated: to be inheritable, early metabolism must have led to an increased rate of growth and division of vesicles and, similarly, transport through vesicle boundaries must have supported the evolution of metabolism. Even though explainin…
