Dielectric Assessment of Epitaxially Grown Al/SiO2/Si Heterojunction
Silicon - Tập 11 - Trang 1875-1883 - 2018
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...
Effects of HEC Concentration on Silicon Polishing
Silicon - Tập 11 - Trang 2059-2066 - 2018
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...
Investigation of the role of Saw damage in Silver catalyzed Metal Assisted Chemical Etching on Multicrystalline Silicon for Solar cell Application
Silicon - - 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...
Identifying Varietal Differences for Silicon Mediated Improvement of Leaf Architecture and Plant Growth in Rice
Silicon - Tập 15 - Trang 6299-6311 - 2023
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. The...
Analytical and Compact Modeling Analysis of a SiGe Hetero-Material Vertical L-Shaped TFET
Silicon - Tập 14 - Trang 2135-2145 - 2021
This paper deals with the development of a novel 2-D analytical modeling of
heterojunction vertical L-shaped tunnel FET for characterisation of surface
potential and drain current. The compact analysis includes the properties of
dual modulation effect with the numerous efforts to predict the characteristics
of current and to discuss the method of device improvement. The dual modulation
effect is u...
A Genetic Algorithm Based Approach for the Extraction of Optical Parameters
Silicon - Tập 8 - Trang 245-250 - 2015
We present the Debye model parameters of four materials which are extensively
used in the field of electronics and photonics. The parameters have been
extracted using a Genetic Algorithm (GA) based technique. We have determined the
complex relative permittivity using the extracted modeling parameters and
compared with the experimentally obtained ones. A very good agreement has been
found in each c...
Analog/RF Performance of Triple Material Gate Stack-Graded Channel Double Gate-Junctionless Strained-silicon MOSFET with Fixed Charges
Silicon - Tập 14 - Trang 7363-7376 - 2021
In this paper, analog/radio frequency (RF) electrical characteristics of triple
material gate stack-graded channel double gate-Junctionless (TMGS-GCDG-JL)
strained-Si (s-Si) MOSFET with fixed charge density is analyzed with the help of
Sentaurus TCAD. By varying the various device parameters, the analog/RF
performance of the proposed TMGS-GCDG-JL s-Si MOSFET is evaluated in terms of
transconductan...
Silicon (Si) Alleviates Iron Deficiency Effects in Sea Barley (Hordeum marinum) by Enhancing Iron Accumulation and Photosystem Activities
Silicon - Tập 14 - Trang 6697-6712 - 2021
Silicon (Si) is a ubiquitous element and the second most abundant after oxygen
in the Earth’s crust. Although silicon is not yet listed among the essential
nutrients for higher plant growth, its beneficial impact on improving crop
development and yield, especially under stressful environments such as iron
deficiency, was well documented. Iron deficiency is a major concern for crop
production mainl...
Effect of Ni Doping on the Structural and Optical Properties of TiO2 Nanoparticles at Various Concentration and Temperature
Silicon - Tập 10 - Trang 2569-2575 - 2018
TiO2 nanopowders doped by Ni were prepared by sol–gel method. The effects of Ni
ion (transition metal ion) doping on the physical structural and optical
properties of TiO2 have been investigated by X-ray diffraction (XRD), scanning
electron microscopy and UV–Vis absorption spectroscopy. XRD results suggest that
adding impurities has a significant effect on anatase phase stability,
crystallinity, a...
Polycyclic Aromatic Hydrocarbons Removal from Aqueous Solution with PABA-MCM-41/Polyethersulfone Mixed Matrix Membranes
Silicon - Tập 14 - Trang 3879-3890 - 2021
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...
