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.

This book was released on 2012-12-06 with total page 245 pages. Available in PDF, EPUB and Kindle. Book excerpt: The workshop on "Optical Properties of Low Dimensional Silicon sL Structures" was held in Meylan, France on March, I yd, 1993. The workshop took place inside the facilities of France Telecom- CNET. Around 45 leading scientists working on this rapidly moving field were in attendance. Principal support was provided by the Advanced Research Workshop Program of the North Atlantic Treaty Organisation (NATO). French Delegation a l'Armement and CNET gave also a small financial grant, the organisational part being undertaken by the SEE and CNET. There is currently intense research activity worldwide devoted to the optical properties of low dimensional silicon structures. This follow the recent discovery of efficient visible photoluminescence (PL) from highly porous silicon. This workshop was intended to bring together all the leading European scientists and laboratories in order to reveal the state of the art and to open new research fields on this subject. A large number of invited talks took place (12) together with regular contribution (20). The speakers were asked to leave nearly 1/3 of the time to the discussion with the audience, and that promoted both formal and informal discussions between the participants.

Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: In this work we investigate the photoluminescence and Raman spectra of porous silicon samples, trying to establish evidence for the mechanism of the luminescence. Although the quantum confinement model seems to correlate well with most of the experimental data presented here, this can not be said for all the samples tested. In particular, it was found that samples etched in the darkness are more consistent with the quantum confinement model, while samples etched with light assistance are more consistent with luminescence from surface species.

This book was released on 2000 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: A survey of recent interest in and time-resolved photoluminescence studies on porous silicon is given and the instrumentation with which time-resolved photoluminescence measurements are acquired is presented. A study of the intensity dependence of the radiative lifetime of porous silicon is performed and a model for the luminescence of the material is formulated and evidence of a molecular luminescence mechanism is presented. It is deduced that a complex energy transfer process between molecules on the surface of porous silicon is responsible for the luminescence that is exhibited by this material.

Download or read book Porous Silicon in Practice written by M. J. Sailor and published by John Wiley & Sons. This book was released on 2012-01-09 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: By means of electrochemical treatment, crystalline silicon can be permeated with tiny, nanostructured pores that entirely change the characteristics and properties of the material. One prominent example of this can be seen in the interaction of porous silicon with living cells, which can be totally unwilling to settle on smooth silicon surfaces but readily adhere to porous silicon, giving rise to great hopes for such future applications as programmable drug delivery or advanced, braincontrolled prosthetics. Porous silicon research is active in the fields of sensors, tissue engineering, medical therapeutics and diagnostics, photovoltaics, rechargeable batteries, energetic materials, photonics, and MEMS (Micro Electro Mechanical Systems). Written by an outstanding, well-recognized expert in the field, this book provides detailed, step-by-step instructions to prepare and characterize the major types of porous silicon. It is intended for those new to the fi eld. Sampling of topics covered: * Principles of Etching Porous Silicon * Etch Cell Construction and Considerations * Photonic Crystals, Microcavities, and Bragg Stacks Etched in Silicon * Preparation of Free-standing Films and Particles of Porous Silicon * Preparation of Photoluminescent Nanoparticles from Porous Silicon * Preparation of Silicon Nanowires by Electrochemical Etch of Silicon * Surface Modifi cation Chemistry and Biochemistry * Measurement of Optical Properties * Measurement of Pore Size, Porosity, Thickness, Surface Area The whole is backed by a generous use of color photographs to illustrate the described procedures in detail, plus a bibliography of further literature pertinent to a wide range of application fi elds. For materials scientists, chemists, physicists, optical physicists, biomaterials scientists, neurobiologists, bioengineers, and graduate students in those fields, as well as those working in the semiconductor industry.

Book excerpt: The authors have shown in their previous studies that applications of x-ray scattering techniques in a transmission geometry open an avenue for in situ structural investigation of silicon/solution, in general, semiconductor/solution interfaces. In these studies, the surface morphological evolution was deduced from x-ray reflectivity measurements and the pore-pore pair-distribution function was obtained from diffuse scattering measurements. The combination of these two techniques provided a complete phenomenological description of the pore formation and growth based on the most fundamental Langevin equation of interface-evolution phenomena, known as Edward-Wilkinson model. In essence, the high-current-density condition, where the surface etching occurs via surface oxidation of silicon and dissolution of the surface oxide, inhibits short-wave length fluctuations and the low-current-density condition, where the surface etching occurs via direct dissolution of H2SiF6 formed at the interface, amplifies fluctuations with length scales of space-charge width. These two conditions are found to be consistent with the sign inversion of coefficient for the curvature dependent term of the Langevin equation. In this study extending the previous studies, the authors will show that the luminescence and the two conditions under which the porous silicon (PS) produced are directly related, based on x-ray and photoluminescence (PL) measurements.
