This book was released on 2014-05-22 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: Master's Thesis from the year 2014 in the subject Physics - Quantum Physics, Shahjalal University of Science and Technology (Department of Physics), course: Nanostructure Physics, language: English, abstract: We have investigated Nanostructure Physics of a Quantum Well (QW) adjacent to a tunnel barrier. On the other side of the QW, we have a barrier layer of semi-infinite thickness. The book contains thorough and complete analytical calculations leading to two transcendental equations obeyed by quasi-bound energy levels of the QW. The book also contains numerical investigation of parametric variations of the quasi-bound energy levels. The variations are quite unexpected. For some values of tunnel barrier width and height, each quasi-bound energy level yields two allowed energy levels. The two equations reduce to those for isolated QW in proper limiting values of parameters. The book contains necessary background on Quantum Mechanics, Microelectronics and Nanostructure Physics to enable readers assimilate the book completely.

This book was released on 2015-02-09 with total page 131 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book deals with pure Nanostructure Physics of a Quantum Well (QW) of general shape adjacent to a tunnel barrier of general shape. On the other side of the QW, we have a barrier of semi-infinite thickness. Using WKB approximation method, the book presents thorough and complete analytical calculations leading to 2 transcendental equations obeyed by quasi-bound energy levels of the non-isolated QW. The 2 general equations have been applied to the cases when the tunnel barrier is rectangular, moderately biased rectangular, triangular and Schottky barrier. Thorough numerical investigations have been reported to bring out parametric variations of the energy levels. For some values of tunnel barrier height and width, the energy levels split into doublets. The book contains a thorough introduction to WKB method; the book also contains necessary background on Microelectronics and Nanostructure Physics to enable readers assimilate the book completely. The 1st 3 chapters are introductory while chapter 4 and 5 are exclusive and original contributions of the book.

Book excerpt: Timely information on scientific and engineering developments occurring in laboratories around the world provides critical input to maintaining the economic and technological strength of the United States. Moreover, sharing this information quickly with other countries can greatly enhance the productivity of scientists and engineers. These are some of the reasons why the National Science Foundation (NSF) has been involved in funding science and technology assessments comparing the United States and foreign countries since the early 1980s. A substantial number of these studies have been conducted by the World Technology Evaluation Center (WTEC) managed by Loyola College through a cooperative agreement with NSF. The National Science and Technology Council (NSTC), Committee on Technology's Interagency Working Group on NanoScience, Engineering and Technology (CT/IWGN) worked with WTEC to develop the scope of this Nanostucture Science and Technology report in an effort to develop a baseline of understanding for how to strategically make Federal nanoscale R&D investments in the coming years. The purpose of the NSTC/WTEC activity is to assess R&D efforts in other countries in specific areas of technology, to compare these efforts and their results to U. S. research in the same areas, and to identify opportunities for international collaboration in precompetitive research. Many U. S. organizations support substantial data gathering and analysis efforts focusing on nations such as Japan. But often the results of these studies are not widely available. At the same time, government and privately sponsored studies that are in the public domain tend to be "input" studies.

Available in PDF, EPUB and Kindle. Book excerpt: The main focus of the book are the physical mechanisms behind the spontaneous formation of ordered nanostructures at semiconductor surfaces. These mechanisms are at the root of recent breakthroughs in advanced nanotechnology of quantum-wire and quantum-dot fabrication. Generic theoretical models are presented addressing formation of all basic types of nanostructures, including periodically faceted surfaces, arrays of step-bunches of equal heights and single- and multi-sheet arrays of both 2- and 3-D strained islands. Decisive experiments on both structural and optical characterization of nanostructures are discussed to verify theoretical models and link them to practical examples.

Book excerpt: This book deals with the electronic and optical properties of two low-dimensional systems: quantum dots and quantum antidots and is divided into two parts. Part one is a self-contained monograph which describes in detail the theoretical and experimental background for exploration of electronic states of the quantum-confined systems. Starting from the single-electron picture of the system, the book describes various experimental methods that provide important information on these systems. Concentrating on many-electron systems, theoretical developments are described in detail and their experimental consequences are also discussed. The field has witnessed an almost explosive growth and some of the future directions of explorations are highlighted towards the end of the monograph. The subject matter is dealt with in such a way that it is both accessible to beginners and useful for expert researchers as a comprehensive review of most of the developments in the field. Furthermore the book contains 37 reprinted articles which have been selected to provide a first-hand picture of the overall developments in the field. The early papers have been arranged to portray the developments chronologically, and the more recent papers provide an overview of future direction in the research.
