Book excerpt: This volume provides a comprehensive review of the experimental and theoretical aspects of the optical and transport properties of nanoporous silicon, their relation to the microscopic structure of nanocrystals, and the application of porous silicon in optical devices. As porous silicon is an ideal substance for the modelling of optical processes in nanocrystalline materials, this volume also is an excellent reference source on the more general subject of the structural and optical properties of nanocrystalline semiconductors.

This book was released on 2015-02-18 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: Even if the discovery of the photoluminescence of porous silicon dates to more than twenty years ago, the research on the optical properties of silicon is still a hot topic. The most recent experimental techniques have allowed the successful synthesis of silicon nanoparticles with narrow size distributions, and the realization of light-emitting silicon devices for technological and biomedical applications. From the theoretical point of view, the physics of silicon nanocrystals still deserves a huge interest. While the quantum confinement effect has been recognized as the main cause of the photoluminescence, many doubts remain on the way in which the phenomenon takes place in real nanocrystals. This book summarizes the result of a work lead by the author at the University of Naples. The density of states, the optical gap, the absorption spectra, the static dielectric constant, the recombination times, are all illustrated for several sets of silicon spheres and ellipsoids, upon changing their size and aspect ratio. The book also reviews previous research work, with special reference to the experimental and theoretical literature on silicon nanocrystals.

This book was released on 2021 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: The discovery of visible photoluminescence (PL) from nanocrystalline porous silicon in 1990 led to extensive research into the mechanisms of the emergent properties, and optimization of these properties, for use in applications. The widespread use of silicon nanoparticles (Si NPs) in commercial applications is currently limited by three main factors: 1) poor radiative recombination efficiency of the interband transition, 2) instability of the interband photoluminescence, and 3) a lack of scalable methods for producing Si NPs that are both highly crystalline and size monodisperse. To address these limitations, this dissertation correlates changes in the photoluminescence properties of hydrogen passivated silicon nanoparticles (H-Si NPs) with changes in the surface structure, as well as develops new synthesis methodology to produce larger, more crystalline Si NPs.

Available in PDF, EPUB and Kindle. Book excerpt: Nowadays, study of silicon-based visible light-emitting devices has increased due to large-scale microelectronic integration. Since then different physical and chemical processes have been performed to convert bulk silicon (Si) into a light-emitting material. From discovery of Photoluminescence (PL) in porous Silicon by Canham, a new field of research was opened in optical properties of the Si nanocrystals (Si-NCs) embedded in a dielectric matrix, such as SRO (silicon-rich oxide) and SRN (silicon-rich nitride). In this respect, SRO films obtained by sputtering technique have proved to be an option for light-emitting capacitors (LECs). For the synthesis of SRO films, growth parameters should be considered; Si-excess, growth temperature and annealing temperature. Such parameters affect generation of radiative defects, distribution of Si-NCs and luminescent properties. In this chapter, we report synthesis, structural and luminescent properties of SRO monolayers and SRO/SiO2 multilayers (MLs) obtained by sputtering technique modifying Si-excess, thickness and thermal treatments.

Download or read book Porous Silicon written by Zhe Chuan Feng and published by World Scientific. This book was released on 1994 with total page 496 pages. Available in PDF, EPUB and Kindle. Book excerpt: Due to the recent discovery of the room-temperature visible light emission from porous silicon (P-Si), a great interest in P-Si and related materials has arisen in the last decade of the 20th century. Crystalline (c-) Si, at the heart of integrated circuits, has an indirect band gap of 1.1 eV, which limits its application in optoelectronics. The visible light emitting P-Si may open a new field combining Si integrated technology and optoelectronics. This book is a comprehensive review of the recent research and development of porous silicon. Strong visible photoluminescence (PL) and electroluminescence (EL) from P-Si and other forms of silicon nanocrystallites (nc-Si) are reviewed. Several proposed mechanisms for the PL from porous silicon such as quantum confinement, amorphicity and molecular PL are studied. The following issues are covered: mechanisms for the visible light emission, physical structures, studies of the PL and EL, correlation of structure and optical studies, surface physics and chemistry, relationships among various forms (P-Si, a-Si, µc-Si), device applications, future developments.

Download or read book Handbook of Porous Silicon written by Leigh Canham and published by Springer. This book was released on 2021-01-14 with total page 1000 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Handbook of Porous Silicon brings together the expertise of a large, international team of almost 100 academic researchers, engineers, and product developers from industry across electronics, medicine, nutrition and consumer care to summarize the field in its entirity with 150 chapters and 5000 references. The volume presents 5 parts which cover fabrication techniques, material properties, characterization techniques, processing and applications. Much attention was given in the the past to its luminescent properties, but increasingly it is the biodegradability, mechanical, thermal and sensing capabilities that are attracting attention. The volume is divided into focussed data reviews with, wherever possible, quantitative rather than qualitative descriptions of both properties and performance. The book is targeted at undergraduates, postgraduates, and experienced researchers.
