Book Synopsis Power GaN Devices by : Matteo Meneghini
Download or read book Power GaN Devices written by Matteo Meneghini and published by Springer. This book was released on 2016-09-08 with total page 383 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the first comprehensive overview of the properties and fabrication methods of GaN-based power transistors, with contributions from the most active research groups in the field. It describes how gallium nitride has emerged as an excellent material for the fabrication of power transistors; thanks to the high energy gap, high breakdown field, and saturation velocity of GaN, these devices can reach breakdown voltages beyond the kV range, and very high switching frequencies, thus being suitable for application in power conversion systems. Based on GaN, switching-mode power converters with efficiency in excess of 99 % have been already demonstrated, thus clearing the way for massive adoption of GaN transistors in the power conversion market. This is expected to have important advantages at both the environmental and economic level, since power conversion losses account for 10 % of global electricity consumption. The first part of the book describes the properties and advantages of gallium nitride compared to conventional semiconductor materials. The second part of the book describes the techniques used for device fabrication, and the methods for GaN-on-Silicon mass production. Specific attention is paid to the three most advanced device structures: lateral transistors, vertical power devices, and nanowire-based HEMTs. Other relevant topics covered by the book are the strategies for normally-off operation, and the problems related to device reliability. The last chapter reviews the switching characteristics of GaN HEMTs based on a systems level approach. This book is a unique reference for people working in the materials, device and power electronics fields; it provides interdisciplinary information on material growth, device fabrication, reliability issues and circuit-level switching investigation.
Book Synopsis Quantum Communications and Cryptography by : Alexander V. Sergienko
Download or read book Quantum Communications and Cryptography written by Alexander V. Sergienko and published by CRC Press. This book was released on 2018-10-03 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: All current methods of secure communication such as public-key cryptography can eventually be broken by faster computing. At the interface of physics and computer science lies a powerful solution for secure communications: quantum cryptography. Because eavesdropping changes the physical nature of the information, users in a quantum exchange can easily detect eavesdroppers. This allows for totally secure random key distribution, a central requirement for use of the one-time pad. Since the one-time pad is theoretically proven to be undecipherable, quantum cryptography is the key to perfect secrecy. Quantum Communications and Cryptography is the first comprehensive review of the past, present, and potential developments in this dynamic field. Leading expert contributors from around the world discuss the scientific foundations, experimental and theoretical developments, and cutting-edge technical and engineering advances in quantum communications and cryptography. The book describes the engineering principles and practical implementations in a real-world metropolitan network as well as physical principles and experimental results of such technologies as entanglement swapping and quantum teleportation. It also offers the first detailed treatment of quantum information processing with continuous variables. Technologies include both free-space and fiber-based communications systems along with the necessary protocols and information processing approaches. Bridging the gap between physics and engineering, Quantum Communications and Cryptography supplies a springboard for further developments and breakthroughs in this rapidly growing area.
Book Synopsis Flexoelectricity in Liquid Crystals by : Agnes Buka
Download or read book Flexoelectricity in Liquid Crystals written by Agnes Buka and published by World Scientific. This book was released on 2013 with total page 299 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book intends to give a state-of-the-art overview of flexoelectricity, a linear physical coupling between mechanical (orientational) deformations and electric polarization, which is specific to systems with orientational order, such as liquid crystals. Chapters written by experts in the field shed light on theoretical as well as experimental aspects of research carried out since the discovery of flexoelectricity. Besides a common macroscopic (continuum) description the microscopic theory of flexoelectricity is also addressed. Electro-optic effects due to or modified by flexoelectricity as well as various (direct and indirect) measurement methods are discussed. Special emphasis is given to the role of flexoelectricity in pattern-forming instabilities. While the main focus of the book lies in flexoelectricity in nematic liquid crystals, peculiarities of other mesophases (bent-core systems, cholesterics, and smectics) are also reviewed. Flexoelectricity has relevance to biological (living) systems and can also offer possibilities for technical applications. The basics of these two interdisciplinary fields are also summarized.

Book Synopsis The Challenge of Change by : Rebecca Hampl
Download or read book The Challenge of Change written by Rebecca Hampl and published by Christian Faith Publishing, Inc.. This book was released on 2022-08-01 with total page 533 pages. Available in PDF, EPUB and Kindle. Book excerpt: At the age of twenty-eight, Marty Ellis is still a bachelor who graduated with a major in journalism and a minor in photojournalism. He enjoys his life with various girlfriends while knocking back drinks in bars, going out to dinner, and rolling in the sheets. Yet inevitably, he grows tired of these surface-level-only feelings, shells out his standard goodbye speech, and moves on. However, using only his body and saying sayonara to his love lifeaEUR(tm)s revolving door is not how he wants to live for the rest of his life. How will he ever know what true love feels like if he doesnaEUR(tm)t ascertain how to actually give it? In what way will he begin to be able to discover the whole package that runs beneath the surface of a woman? Unexpectedly, Marty is blindsided when his best friend invites him to leave New Jersey for a weekend trip. Lauren Morris is a beautiful thirty-two-year-old woman who, after graduating at the age of twenty-one with a masteraEUR(tm)s degree in business, took a huge leap of faith and purchased an old farmhouse in Vermont. After ten years of hard work and sweat equity, she has transformed it into a beautiful inn that has become extremely lucrative. But winter is fast approaching, and she is dreading that feeling of loneliness that is connected to darkened afternoons and long, empty nights. Will a man ever enter her life? One that she could love and perhaps be with until death due them part? After meeting Marty, Lauren begins to consider if this man might be the one she has been waiting for her whole life. But then again, she is older than he is; long distance relationships hardly ever work out; and sudden heartbreaking unforeseen events rock both of their worlds. And if they do fall in love, which one of them will have to make the ultimate sacrifice and give up what theyaEUR(tm)ve worked so hard to achieve in order to be together? With so many changes causing so many challenges, will they get through them together, or will one push the other away?
