Book Synopsis Towards the First Silicon Laser by : Lorenzo Pavesi
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.

Book Synopsis Spectroscopy: Theory and Applications by : Charles Burke
Download or read book Spectroscopy: Theory and Applications written by Charles Burke and published by . This book was released on 2021-10-19 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: The nature of interaction between matter and electromagnetic radiation can be understood with the technique of spectroscopy. It is an exploratory tool used in the fields of astronomy, physics and chemistry to study the composition, electronic structure and physical structure of matter at the atomic and molecular scales, even over astronomical distances. Spectroscopy can be studied with variations in the type of radiative energy used to interact with matter, the nature of the interaction and the type of material used. Depending on these interactions, spectroscopy can be of different types, such as microwave spectroscopy, infrared spectroscopy, electron spectroscopy, absorption spectroscopy, emission spectroscopy, atomic spectroscopy, molecular spectroscopy, etc. It may be used for varied purposes, such as measuring toxic compounds in blood or different compounds in food, exploring electronic structures and conducting elemental analysis, etc. Spectrometers, spectral analyzers and spectrophotometers are some common devices used to achieve spectral measurement. This book unravels the recent studies in spectroscopy. Also included in this book is a detailed explanation of the various techniques and applications of this field. For all those who are interested in this technology, this book can prove to be an essential guide.
Book Synopsis Thermal Transport in Semiconductors by : Pol Torres Alvarez
Download or read book Thermal Transport in Semiconductors written by Pol Torres Alvarez and published by . This book was released on 2017 with total page 187 pages. Available in PDF, EPUB and Kindle. Book excerpt: La majoria dels aparells electrònics utilitzats avui en dia tenen components basats en materials semiconductors, els quals poden ser utilitzats en un ampli rang d'aplicacions, des de transistors fins a generadors termoelèctrics o fotovoltaics. Per tal de millorar el rendiment d'aquests aparells i reduir-ne la mida és necessari conèixer la física dels materials que el formen. Quan la mida es redueix, les propietats físiques dels materials canvia, i en especial la transferència de calor a través dels dispositius. Canvis en la temperatura poden afectar directament totes les altres propietats físiques. En aquesta tesi, el transport tèrmic és analitzat des de material bulk (mides grans) fins la nanoescala sota diferents aproximacions utilitzant primers principis. Per una banda, la conductivitat tèrmica en bulk s'estudia en el marc cinètic-col·lectiu, on l'equació de transport de Boltzmann (BTE) per fonons es soluciona en el model de Guyer i Krumhansl. Aquesta solució es coneguda com Kinetic Collective Model (KCM, model cinètic col·lectiu). El KCM, el qual separa la conductivitat tèrmica en una contribució cinètica i una col·lectiva, ha permès obtenir la conductivitat tèrmica d'un gran nombre de semiconductors, coincidint perfectament amb altres solucions actuals de la BTE, i el que és més important, amb dades experimentals. Per altra banda, per mostres de mida petita, s'han considerat dues aproximacions per estudiar els efectes de la superfície. En primer lloc s'ha utilitzat una aproximació cinètica-col·lectiva. En aquest cas, en el règim cinètic, els efectes de superfície es consideren com un mecanisme microscòpic de col·lisions, mentre que en el règim col·lectiu es calculen tenint en compte consideracions hidrodinàmiques. La limitació d'aquesta aproximació per geometries complexes ha promogut el desenvolupament del segon cas: un marc completament hidrodinàmic de transport tèrmic. Una equació hidrodinàmica de transport s'ha desenvolupat a partir del model de Guyer i Krumhansl i de la termodinàmica irreversible estesa (EIT). Aquesta equació hidrodinàmica s'ha utilitzat en primer lloc per estudiar geometries simples com nanofils amb un model de conductivitat tèrmica efectiva. A més, la utilització de condicions de contorn genèriques ha permès utilitzar la equació hidrodinàmica del KCM en càlculs d'elements finits per estudiar geometries complexes. Finalment s'ha fer un anàlisi de l'espectre de fonons i s'ha proposat la seva importància a l'hora de tractar processos transitori. Tots els temes tractats en aquesta tesi en l'àmbit del KCM s'han discutit i comprat amb altres models de transport tèrmic. Paral·lel al desenvolupament del model hidrodinàmic, les expressions de transport en l'aproximació de superfície cinètica-col·lectiva així com paràmetres hidrodinàmics s'han implementat en un software de codi lliure. Compartir el model com a eina per predir el transport tèrmic permetrà establir ponts entre la física del transport tèrmic des del punt de vista microscòpic al macroscòpic.
Book Synopsis Nanostructures unidimensionnelles en carbure de silicium by : Laurence Latu-Romain
Download or read book Nanostructures unidimensionnelles en carbure de silicium written by Laurence Latu-Romain and published by ISTE Group. This book was released on 2014-10-01 with total page 113 pages. Available in PDF, EPUB and Kindle. Book excerpt: Les nanostructures unidimensionnelles (1D) en carbure de silicium (SiC) sont des objets séduisants pour la communauté scientifique du fait de l'association des propriétés du matériau et des basses dimensionnalités. Le carbure de silicium a en effet des propriétés physico-chimiques et électroniques très intéressantes, notamment du fait de sa biocompatibilité. Les nanostructures 1D comme les nanofils et les nanotubes sont remarquables grâce à leur rapport surface sur volume élevé et leurs propriétés parfois exceptionnelles par rapport à celles du matériau massif. Consacré aux nanostructures 1D en SiC, cet ouvrage explicite les propriétés et les différentes méthodes d’élaboration de ces nanostructures. Il détaille la carburation de nanofils de silicium, un procédé de croissance original permettant d’obtenir des nanofils coeur-coquille Si-SiC et des nanotubes SiC de très bonne qualité cristalline, grâce à la maîtrise de l’exo-diffusion du Si. Les possibles applications de ces nanostructures sont également étudiées.
