Silicon oxides: a promising family of anode materials for lithium-ion batteries.

Chemical Society Reviews, 2019
Silicon oxides have been recognized as a promising family of anode materials for high-energy lithium-ion batteries (LIBs) owing to their abundant reserve, low cost, environmental friendliness, easy synthesis, and high theoretical capacity.

Silicon/silicon oxide and silicon/silicon nitride multilayers for XUV optical applications

SPIE Proceedings, 1991
Si/Si02 and Si/Si3N4 multilayers have been fabricated using a locally made reactive diode if-sputtering systern. 'Ihe layer alternation is obtained by modulating a partial pressure of oxygen or nitrogen near the sample using a silicon target and argon as sputtering gas.

SILICON

Annual Review of Plant Physiology and Plant Molecular Biology, 1999
▪ Abstract  Silicon is present in plants in amounts equivalent to those of such macronutrient elements as calcium, magnesium, and phosphorus, and in grasses often at higher levels than any other inorganic constituent. Yet except for certain algae, including prominently the diatoms, and the Equisetaceae (horsetails or scouring rushes), it is not ...

High-performance hybrid silicon and lithium niobate Mach–Zehnder modulators for 100 Gbit s−1 and beyond

Nature Photonics, 2018
Optical modulators are at the heart of optical communication links. Ideally, they should feature low loss, low drive voltage, large bandwidth, high linearity, compact footprint and low manufacturing cost.

Copper in silicon

Physical Review Letters, 1990
The presence of Cu atoms in p-type Si is detected via their characteristic electric-field gradients measured at the radioactive acceptor $^{111}\mathrm{In}$${/}^{111}$Cd by the perturbed \ensuremath{\gamma}\ensuremath{\gamma} angular correlation technique.

Silicon Photonics: silicon nitride versus silicon-on-insulator

Optical Fiber Communication Conference, 2016
Silicon photonics typically builds on a silicon-on-insulator based high-index-contrast waveguide system. Silicon nitride provides an alternative moderate-index-contrast system that is manufacturable in the same CMOS environment. This paper discusses the relative benefits of both platforms.

Local Oscillations of Silicon–Silicon Bonds in Silicon Nitride

Technical Physics Letters, 2018
Raman spectra of films of nearly stoichiometric amorphous silicon nitride (a-Si3N4) reveal a contribution due to local oscillations of silicon–silicon (Si–Si) bonds. This observation directly confirms that the almost stoichiometric a-Si3N4 contains Si–Si bonds, which, according to theoretical predictions, act as electron and hole traps that are ...

The donor concentration in silicon implanted silicon and silicon on sapphire [PDF]

IEEE SOS/SOI Technology Conference, 2003
Summary form only given. The effective number of carriers in self-implanted silicon on sapphire is studied. The penetration of the materials by the double solid phase epitaxy method (DSPE) is discussed. In order to measure the depth distribution of the implantation-induced donors, silicon was implanted in 2 ohm cm n ...

From Silicon Cell to Silicon Human

2011
This chapter discusses the silicon cell paradigm , i.e. the existing systems biology activity of making experiment-based computer replica of parts of biological systems. Now that such mathematical models are accessible to in silico experimentation through the World-Wide Web , a new future has come to biology.

Functional nanoscale electronic devices assembled using silicon nanowire building blocks.

Science, 2001
Because semiconductor nanowires can transport electrons and holes, they could function as building blocks for nanoscale electronics assembled without the need for complex and costly fabrication facilities.
