“…Interfacial oxide layer may also be the possible cause for a higher ideality factor, where this result is similar to [14], while the barrier height decreased with the increasing etching current density. This etching current is enhanced in accordance to the interface layer between PSi/c-Si which has large amount of pinning, thus acting as a defect in the interface and causes to rise the saturation etching current density, thereby reducing the barrier height of PSi/c-Si, and this agrees with [15,16].…”

In this paper porous silicon sample that can be used as a photodetector was prepared at fixed etching time of 15min and different etching current density (15, 17, 19 and 21) mA/cm 2 . Electrical properties of Al / PSi / p-Si /Al photodetector were studied. We found that the I-V characteristics dependence of the etching current density relates to the PSi pores development, where the pore diameter in PSi structure might get enlarged due to the enhancement of the etching current density. The ideality factor ranges around (6.8-4.2) while the barrier height decreased with the increasing etching current density and the etching time as the interface layer between PSi/c-Si has large amount of pinning. Then the C-V characteristics of the sandwich structure are described. When the etching current densities are increased, it reduces the capacitance of the PSi layer. It thus increases the thickness of the depletion region which in turn results in development of built-in potential.

The main aim of our project is to design a chemical plant for production of hydrogen peroxide (H 2 O 2 ) in order to achieve a capacity of 10,000 ton per year. The raw materials used in this plant are 2-ethyl anthraquinone, hydrogen, 2-ethyl hydroquinone and oxygen. Selection of the most suitable method for production of hydrogen peroxide is the important task for a design engineer. In addition, world market of hydrogen peroxide and the prices of feedstock and its impact on process selection are addressed. Moreover, the choosing of best methodologies were investigated and compared where one method needed to be assigned as the production method. Material balance and energy balance, design of equipment's plant, process engineering and economics, plant layout, storage and handling were studied. Finally the results are compared using simulation software HYSYS.

“…The probability of recombination of e and h is higher in very small structures (quantum confinement effects), leading to higher emissions. High PL intensity is the result of the conversion of the material energy gap conduction from indirect to quasidirect [12,13]. The quantum dimension of the structure in the sample favours PL shifting towards shorter wavelengths.…”

This study presents porous silicon (PSi) samples preparation by electrochemical etching method of p type silicon wafers of 100 degree orientation with different etching time (15, 17, 19, 21)min and with fixed electrolyte solution (40% HF: 99.98% CH 3 OH) (1:1). The optical property is described by PhotoLuminescence (PL). The PL measurements of PSi samples show that the energy gap increased after the etching process, and all samples exhibit blue shift with the increasing PL intensity.
