Book SynopsisESSENTIALS OF SEMICONDUCTOR DEVICE PHYSICS An introductory semiconductor device physics textbook that is accessible to readers without a background in statistical physics I wish this book had been available when I needed to make a Semiconductor class myself a few years ago [...] A very nice aspect is that some concepts (e.g. density of states) are explained in a way that I have not seen elsewhere. These types of unconventional approaches are very valuable for a teacher.(Bjorn Maes, University of Mons, Belgium) [...] the author offers an accessible description of statistical analysis and adopts it to explain the core properties of semiconductors. [...] [He] uses interesting metaphors and analogies to exemplify some of the most difficult notions, in an innovative and engaging way. (Andrea di Falco, University of St. Andrews, UK) The subject of this book is the physics of semiconductor devices, which is an important topic in engineering and physics because it forms the background for electronic and optoelectronic devices, including solar cells. The author aims to provide students and teachers with a concise text that focuses on semiconductor devices and covers the necessary background in statistical physics. This text introduces the key prerequisite knowledge in a simple, clear, and friendly manner. It distills the key concepts of semiconductor devices down to their essentials, enabling students to master this key subject in engineering, physics, and materials. The subject matter treated in this book is directly connected to the physics of p-n junctions and solar cells, which has become a topic of intense interest in the last decade. Sample topics covered within the text include: Chemical potential, Fermi level, Fermi-Dirac distribution, drift current and diffusion current. The physics of semiconductors, band theory and intuitive derivations of the concentration of charge carriers. The p-n junction, with qualitative analysis preceding the mathematical descriptions. A derivation of the current vs voltage relation in p-n junctions (Shockley equation). Important applications of p-n junctions, including solar cellsThe two main types of transistors: Bipolar Junction Transistors (BJT) and Metal Oxide Semiconductor Field Effect Transistors (MOSFET) For students and instructors, it may be used as a primary textbook for an introductory semiconductor device physics course and is suitable for a course of approximately 30-50 hours. Scientists studying and researching semiconductor devices in general, and solar cells in particular, will also benefit from the clear and intuitive explanations found in this book.Table of ContentsPreface 1 Concepts of Statistical Physics 1.1 Introduction 1.2 Thermal Equilibrium 1.3 Partition function - Part I 1.4 Diffusive equilibrium and the chemical potential 1.5 The partition function, Part II 1.6 Example of application: energy and number of elements of a system 1.7 The Fermi-Dirac distribution 1.8 Analogy between the systems “box” and “coins” 1.9 Concentration of electrons and Fermi level 1.10 Transport 1.11 Relationship between current and concentration of particles (continuity equation) 1.12 Suggestions for further reading 1.13 Exercises 2 – Semiconductors 2.1 Band Theory 2.2 Electrons and holes 2.3 Concentration of free electrons 2.4 Density of states 2.5 Concentration of holes and Fermi level 2.6 Extrinsic semiconductors (doping) 2. 7 Exercises 3 Introduction to semiconductor devices: the p-n junction 3.1 p-n junction in thermodynamic equilibrium – qualitative description 3.2 p-n junction in thermodynamic equilibrium – quantitative description 3.3 Systems outside thermodynamic equilibrium: the quasi-Fermi levels. 3.4 Qualitative description of the relationship between current and voltage in a p-n junction 3.5 The current vs voltage relationship in a p-n junction (Shockley’s equation) 3.6 Suggestions for further reading 3.7 Exercises 4 Photovoltaic devices (mainly solar cells) 4.1 Solar cells and photodetectors 4.2 Physical principles 4.3 The equivalent circuit 4.4 The I x V curve and the fill-factor 4.5 Efficiency of solar cells and the theoretical limit 4.6 Connections of solar cells 4.7 Suggestions for further reading 4.8 Exercises 5 Transistors 5.1 The Bipolar Junction Transistor (BJT) 5.1.1 Physical principles of the BJT 5.1.2 The beta parameter and the relationship between emitter, collector and base currents 5.1.3 Relationship between IC and VCE and the Early effect 5.1.4 The BJT as an amplifier 5.2 The MOSFET 5.2.1 Physical principles 5.2.3 Examples of applications of MOSFETS: logic inverters and logic gates 5.3 Suggestions for further reading 5.4 Exercises Appendix: Geometrical interpretation of the chemical potential and free energy

Book SynopsisControl over Communication Networks Advanced and systematic examination of the design and analysis of networked control systems and multi-agent systems Control Over Communication Networks provides a systematic and nearly self-contained description of the analysis and design of networked control systems (NCSs) and multi-agent systems (MASs) over imperfect communication networks, with a primary focus on fading channels and delayed channels. The text characterizes the effect of communication channels on the stability and performance of NCSs, and further studies the joint impact of communication channels and network topology on the consensus of MASs. By integrating communication and control theory, the four highly-qualified authors present fundamental results concerning the stabilization of NCSs over power-constrained fading channels and Gaussian

Book SynopsisPresents the science of colour from new perspectives and outlines results obtained from the authors' work in the mathematical theory of colour This innovative volume summarizes existing knowledge in the field, attempting to present as much data as possible about colour, accumulated in various branches of science (physics, phychophysics, colorimetry, physiology) from a unified theoretical position. Written by a colour specialist and a professional mathematician, the book offers a new theoretical framework based on functional analysis and convex analysis. Employing these branches of mathematics, instead of more conventional linear algebra, allows them to provide the knowledge required for developing techniques to measure colour appearance to the standards adopted in colorimetric measurements. The authors describe the mathematics in a language that is understandable for colour specialists and include a detailed overview of all chapters to help readers not familiar with colour science. Divided into two parts, the book first covers various key aspects of light colour, such as colour stimulus space, colour mechanisms, colour detection and discrimination, light-colour perception typology, and light metamerism. The second part focuses on object colour, featuring detailed coverage of object-colour perception in single- and multiple-illuminant scenes, object-colour solid, colour constancy, metamer mismatching, object-colour indeterminacy and more. Throughout the book, the authors combine differential geometry and topology with the scientific principles on which colour measurement and specification are currently based and applied in industrial applications. Presents a unique compilation of the author's substantial contributions to colour scienceOffers a new approach to colour perception and measurement, developing the theoretical framework used in colorimetryBridges the gap between colour engineering and a coherent mathematical theory of colourOutlines mathematical foundations applicable to the colour vision of humans and animals as well as technologies equipped with artificial photosensorsContains algorithms for solving various problems in colour science, such as the mathematical problem of describing metameric lightsFormulates all results to be accessible to non-mathematicians and colour specialistsFoundations of Colour Science: From Colorimetry to Perception is an invaluable resource for academics, researchers, industry professionals and undergraduate and graduate students with interest in a mathematical approach to the science of colour.Table of Contents1 Outline for readers in a hurry 1 I Light colour 81 2 Colour

Book SynopsisGraph Database and Graph Computing for Power System Analysis Understand a new way to model power systems with this comprehensive and practical guide Graph databases have become one of the essential tools for managing large data systems. Their structure improves over traditional table-based relational databases in that it reconciles more closely to the inherent physics of a power system, enabling it to model the components and the network of a power system in an organic way. The authors' pioneering research has demonstrated the effectiveness and the potential of graph data management and graph computing to transform power system analysis. Graph Database and Graph Computing for Power System Analysis presents a comprehensive and accessible introduction to this research and its emerging applications. Programs and applications conventionally modeled for traditional relational databases are reconceived here to incorporate graph computing.

Book SynopsisProviding a complete description of modern tactical military communications and networks technology, this book systematically compares tactical military communications techniques with their commercial equivalents, pointing out similarities and differences. In particular it examines each layer of the protocol stack and shows how specific tactical and security requirements result in changes from the commercial approach. The author systematically leads readers through this complex topic, firstly providing background on the architectural approach upon which the analysis will be based, and then going into detail on tactical wireless communications and networking technologies and techniques. Structured progressively: for readers needing an overall view; for those looking at the communications aspects (lower layers of the protocol stack); and for users interested in the networking aspects (higher layers of the protocol stack) Presents approachTrade Review“I would like to recommend the book for graduate students, engineers and researchers interested in a general understanding of military wireless network technologies, architectures, and challenges facing future generations of this type of networks.” (IEEE Communications Magazine, 1 July 2014) Table of ContentsAbout the Author xi Foreword xiii Preface xv List of Acronyms xvii Part I Theoretical Basis 1 Introduction 3 1.1 The OSI Model 4 1.2 From Network Layer to IP Layer 6 1.3 Pitfall of the OSI Model 7 1.4 Tactical Networks Layers 9 1.5 Historical Perspective 10 Bibliography 11 2 The Physical Layer 13 2.1 Modulation 13 2.1.1 Signal-in-Space (SiS) 16 2.2 Signal Detection 22 2.2.1 Signal Detection in Two-Dimensional Space 24 2.2.2 Multidimensional Constellations for AWGN 28 2.3 Non-Coherent Demodulation 29 2.4 Signal Fading 29 2.5 Power Spectrum 31 2.6 Spread Spectrum Modulation 34 2.6.1 Direct Sequence Spread Spectrum 35 2.6.2 Frequency Hopping Spread Spectrum 38 2.7 Concluding Remarks 40 2.7.1 What Happens Before Modulation and After Demodulation?
