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 Towards the First Silicon Laser written by Lorenzo Pavesi and published by Springer Science & Business Media. This book was released on 2003-03-31 with total page 502 pages. Available in PDF, EPUB and Kindle. Book excerpt: Silicon, the leading material in microelectronics during the last four decades, also promises to be the key material in the future. Despite many claims that silicon technology has reached fundamental limits, the performance of silicon microelectronics continues to improve steadily. The same holds for almost all the applications for which Si was considered to be unsuitable. The main exception to this positive trend is the silicon laser, which has not been demonstrated to date. The main reason for this comes from a fundamental limitation related to the indirect nature of the Si band-gap. In the recent past, many different approaches have been taken to achieve this goal: dislocated silicon, extremely pure silicon, silicon nanocrystals, porous silicon, Er doped Si-Ge, SiGe alloys and multiquantum wells, SiGe quantum dots, SiGe quantum cascade structures, shallow impurity centers in silicon and Er doped silicon. All of these are abundantly illustrated in the present book.
Download or read book Luminescence Spectroscopy of Semiconductors written by Ivan Pelant and published by OUP Oxford. This book was released on 2012-02-02 with total page 557 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reviews up-to-date ideas of how the luminescence radiation in semiconductors originates and how to analyze it experimentally. The book fills a gap between general textbooks on optical properties of solids and specialized monographs on luminescence. It is unique in its coherent treatment of the phenomenon of luminescence from the very introductory definitions, from light emission in bulk crystalline and amorphous materials to the advanced chapters that deal with semiconductor nano objects, including spectroscopy of individual nanocrystals. The theory of radiative recombination channels in semiconductors is considered on a level of intuitive physical understanding rather than rigorous quantum mechanical treatment. The book is based on teaching and written in the style of a graduate text with plenty of tutorial material, illustrations, and problem sets at chapter ends. It is designed predominantly for students in physics, optics, optoelectronics and materials science.

Download or read book Porous Silicon Science and Technology written by Jean-Claude Vial and published by Springer Science & Business Media. This book was released on 2013-03-14 with total page 363 pages. Available in PDF, EPUB and Kindle. Book excerpt: The discovery of bright visible light emission from porous silicon has opened the door to various nanometer sized silicon structures where the confinement of carriers gives rise to interesting physical properties. While the high efficiency of the light emission in the visible range is the common and the most prominent feature, their structures display similar properties with other highly divided materials (even non semiconductors), and then justify a multidisciplinary approach. This along with potential applications has attracted a large number of researchers followed by students to be trained. Until now international conferences have provided the exchange of information but have remained highly specialised so it was time to give thought to the organisation of topical and advanced lectures where the multidisciplinarity and the didactic approach are paramount. L'ecole des Houches was ideally devoted to that purpose. The meeting : " Luminescence of porous silicon and silicon nanostructures" was the first international school on this topic but some aspects in the organisation and the attendance have given an international workshop flavor to it. The school by itself has trained 82 «students», most of them were students starting their Ph. D thesis. 50% were French citizens and the other represented countries were Germany, England, USA, Czechoslovakia, The Netherlands, Italy, Japan, Poland, Spain, Canada, Brazil, India and Russia.
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).

Download or read book Light Emission from Silicon Progress Towards Si based Optoelectronics written by Jan Linnros and published by Elsevier Publishing Company. This book was released on 1999 with total page 558 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains the papers presented at Symposium B of the 1998 spring meeting of the European Materials Research Society (E-MRS). The symposium attracted well over 100 scientists engaged in one common goal - that of developing efficient light emitting Si-based structures. This included various technical approaches such as porous silicon, Si nanocrystals, rare-earth doping of Si, light emitting silicides, Si-based multilayer and alloy structures and SiGe structures. In this respect, the meeting had a more multidisciplinary approach than previous meetings, the main idea being a fruitful comparison of the different techniques that would also stimulate cross-disciplinary research. Generally, presentations at the conference revealed high scientific quality and several new findings and refinements of existing techniques were disclosed. One example was the much-debated report of optical gain from a structure containing Si nanocrystals. Another example was the dramatically improved stability of derivatised porous silicon. The technique of producing porous Si microcavities has been refined such that cavities of high optical quality may now be fabricated. The latest material to emerge as a candidate for a Si-based light emitting device has been iron silicide and room temperature operation has been reported. The interest is further motivated by the prospect of obtaining direct bandgap emission. The 90 collected papers represent about 80% of the submitted papers out of more than 140 accepted abstracts. The papers have been grouped according to subject although no ordering within each subgroup has been attempted. All invited papers have been placed in the foremost section to serve as reviews in each separate field.
