Dielectric Assessment of Epitaxially Grown Al/SiO2/Si HeterojunctionSilicon - Tập 11 - Trang 1875-1883 - 2018
A. Ashery, Mohamed M. M. Elnasharty
The dielectric properties of metal–oxide–semiconductor Al/SiO2/p-Si, MOS, heterojunction were studied in the frequency range 40 Hz–20 MHz and in the temperature range 30–90C using 1 Vrms test signal. Experimental results verified that various dielectric parameters and ac conductivity (sac) are strong function of frequency and temperature. The values of both real and imaginary parts of permittivity...... hiện toàn bộ
Effects of HEC Concentration on Silicon PolishingSilicon - Tập 11 - Trang 2059-2066 - 2018
Jin Yang, Shibin Lu, Haibo Wang, Min Fan, Xianwei Jiang, Zhongxiang Zhang
Hydroxyethyl cellulose (HEC) is believed to effectively reduce haze level in silicon final polishing. We find that the removal rate(RR) and roughness of the polishing are very sensitive to the concentration of HEC, which can be divided into two concentration ranges. Its machanism is not only absorption occurence on silicon surface but also related to HEC colloid properties. Evidence has shown that...... hiện toàn bộ
Investigation of the role of Saw damage in Silver catalyzed Metal Assisted Chemical Etching on Multicrystalline Silicon for Solar cell ApplicationSilicon - - Trang 1-14 - 2023

This work investigates how the saw damage from different processes affected the Silver-catalyzed Metal Assisted Chemical Etching. Multicrystalline silicon ingot was grown from a 15 kg Directional Solidification (DS) furnace. The wafers were extricated from silicon brick by using the blade or diamond wire cutting machine which leaves the saw damage in the substrate of the wafer. Surface texturizati...... hiện toàn bộ
Identifying Varietal Differences for Silicon Mediated Improvement of Leaf Architecture and Plant Growth in RiceSilicon - Tập 15 - Trang 6299-6311 - 2023
Mansura Akter Sume, Mohammad Asadul Haque, Aysha Mobaswera, Md Fazlul Hoque, Md Jahiruddin, Richard William Bell
Silicon (Si) is acquainted as an adjuvant plant nutrient element especially on rice; however, the differences among rice varieties for Si response yet not documented at coastal ecosystem like in south and south-east Asia. The objective of the experiment was to identify differences among rice varieties for Si mediated improvement of leaf erectness and its relationship to plant growth and yield. Th...... hiện toàn bộ

Polycyclic Aromatic Hydrocarbons Removal from Aqueous Solution with PABA-MCM-41/Polyethersulfone Mixed Matrix MembranesSilicon - Tập 14 - Trang 3879-3890 - 2021
José Arnaldo S. Costa, Victor H. V. Sarmento, Luciane P. C. Romão, Caio M. Paranhos
Polycyclic aromatic hydrocarbons (PAHs) are one of the most recalcitrant pollutant originated from the burning of coal, petroleum, and other fossil fuels. The human exposure to PAHs may contribute to develop several carcinogenesis mechanisms. The aim of the present study was to develop a mixed matrix membrane (MMM) based on polyethersulfone (PES) and functionalized mesoporous material for the reme...... hiện toàn bộ
Spectroscopic Studies on Nano-Single Crystal BiVO4 Glass Ceramic as Dye Degradation for Wastewater PurificationSilicon - Tập 10 - Trang 509-517 - 2017
M. A. Marzouk, A. A. El-Kheshen, Sohair A. Sayed Ahmed, Reham M. M. Aboelenin
Five bismuth vanadate glass samples and their corresponding glass-ceramics containing Bi2O3 ranging between 10-40 mol% were prepared by melting and controlled heat treatment, respectively. The prepared samples were investigated by XRD, FTIR, and TEM. Some specimens were also subjected to magnetization testing. The glass samples containing higher content of V2O5exhibited precipitation of BiVO4 phas...... hiện toàn bộ
