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 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.

Available in PDF, EPUB and Kindle. Book excerpt: This volume presents the most recent results concerning the various approaches to obtaining light emission from silicon. This dream of silicon technologists is inspired by the fact that an efficient and stable silicon light emitting device would open the way to the production of monolithic optoelectronic integrated circuits, that were based entirely upon silicon. In fact, some of the main building blocks of optoelectronic devices, such as waveguides and photodetectors have already been developed by using silicon technology. The above possibility would sharply reduce the price of optoelectronic circuits as compared with hybrid ones.

This book was released on 2003-11-12 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: A fascinating insight into the state-of-the-art in silicon microphotonics and on what we can expect in the near future. The book presents an overview of the current understanding of getting light from silicon. It concentrates mainly on low dimensional silicon structures, like quantum dots, wires and wells, but covers also alternative approaches like porous silicon and the doping of silicon with rare-earths. The emphasis is on the experimental and theoretical achievements concerning the optoelectronic properties of confined silicon structures obtained during recent years. Silicon based photonic crystals are in particular considered. An in depth discussion of the route towards a silicon laser is presented.

Book excerpt: An important characteristic of the scientific activity surrounding the light emission from silicon is its ability to progress quickly in many different directions and to open new questions as soon as it is tried to answer others. Researchers have now the choice between different and concurrent explanations of the visible light emission. The characterisation of the material and optical properties are more and more advanced. New silicon structures show similar properties. Abinitio calculations are able to handle some aspects of the light emission. The application of porous silicon for electro-optical devices also shows progress, the efficiency of electroluminescence has been enhanced and it can be tuned continuously over the whole visible range, the photoluminesence can be modulated by an external voltage, etc. All these aspects and numerous others are presented in this book.

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.

Book excerpt: "The electrochemical etching of crystalline silicon in hydrofluoric acid based solutions has been found to produce a porous layer, termed porous silicon (PS), which is found to exhibit photoluminescence (PL) and electroluminescence (EL) in the visible region. While the luminescence mechanism is the subject of much debate, the potential for this material is enormous as it could usher in a new generation of silicon-based optoelectronic devices. An electrolytic cell capable of producing luminescent layers of porous silicon over large area silicon wafers has been designed and fabricated. The stability of the PL of PS after subjection to standard microelectronic processing steps, namely thermal oxidation, ion implantation, and reactive ion etching has been investigated. Changes in the PL intensity as well as shifts in the PL wavelengths observed after processing support the quantum confinement and surface states theories for the luminescence. These results also support the possibility of integrating PS into standard silicon integrated circuit processing. For the study of EL, Au/PS Schottky, ITO/PS heterojunction and PS pn junction diodes have been fabricated. EL efficiencies in the range of 10~5 to 10"7 have been determined for these devices. The diodes typically exhibit extremely high series resistance and ideality factor values. These results are direct consequences of the large non-planar surface area of PS yielding poor electrical contacts and high surface state densities. These factors need to be drastically improved to obtain efficient EL in PS devices. A unique process capable of obtaining 5 u.m wide lines of luminescent porous silicon in close proximity to device quality polished silicon is also presented."--Abstract.
