Polyaniline (PANI) is one of the most common and widely studied conducting polymers due to its excellent electro-chemical and electrical properties and its various applications in areas such as solar cell technologies, drug delivery, organic light emitting diodes (OLEDs), field-effect transistors (FETs), sensors, electro-chromic display, etc. PANI thin films play an important role in energy storage and conversion devices and show great potential in the supercapacitors owing to their high specific capacitance, high flexibility, and low cost. However, no in-depth information about this emerging PANI thin film technology is available. Properties, Techniques, and Applications of Polyaniline (PANI) Thin Films: Emerging Research and Opportunities is an essential publication that focuses on high-throughput synthesis of PANI thin films and their characterization techniques. The book also covers promising applications of PANI thin films and applications including solar cells. Featuring research on topics such as solar cells, post-synthesis treatments, and physiochemistry, this book is ideally designed for scientists, industry practitioners, engineers, managers, academicians, researchers, and students seeking coverage in the areas of polymeric applications.

Semiconductors and Modern Electronics is a brief introduction to the physics behind semiconductor technologies. Chuck Winrich, a physics professor at Babson College, explores the topic of semiconductors from a qualitative approach to understanding the theories and models used to explain semiconductor devices. Applications of semiconductors are explored and understood through the models developed in the book. The qualitative approach in this book is intended to bring the advanced ideas behind semiconductors to the broader audience of students who will not major in physics. Much of the inspiration for this book comes from Dr. Winrich's experience teaching a general electronics course to students majoring in business. The goal of that class, and this book, is to bring forward the science behind semiconductors, and then to look at how that science affects the lives of people.

This thesis presents and discusses recent optical low-temperature experiments on disordered NbN, granular Al thin-films, and the heavy-fermion compound CeCoIn5, offering a unified picture of quantum-critical superconductivity. It provides a concise introduction to the respective theoretical models employed to interpret the experimental results, and guides readers through in-depth calculations supplemented with supportive figures in order to both retrace the interpretations and span the bridge between experiment and state-of-the art theory.

At the heart of modern power electronics converters are power semiconductor switching devices. The emergence of wide bandgap (WBG) semiconductor devices, including silicon carbide and gallium nitride, promises power electronics converters with higher efficiency, smaller size, lighter weight, and lower cost than converters using the established silicon-based devices. However, WBG devices pose new challenges for converter design and require more careful characterization, in particular due to their fast switching speed and more stringent need for protection. Characterization of Wide Bandgap Power Semiconductor Devices presents comprehensive methods with examples for the characterization of this important class of power devices. After an introduction, the book covers pulsed static characterization; junction capacitance characterization; fundamentals of dynamic characterization; gate drive for dynamic characterization; layout design and parasitic management; protection design for double pulse test; measurement and data processing for dynamic characterization; cross-talk consideration; impact of three-phase system; and topology considerations.

This book provides an introduction to quantum cascade lasers, including the basic underlying models used to describe the device. It aims at giving a synthetic view of the topic including the aspects of the physics, the technology, and the use of the device. It should also provide a guide for the application engineer to use this device in systems. The book is based on lecture notes of a class given for Masters and beginning PhD students. The idea is to provide an introduction to the new and exciting developments that intersubband transitions have brought to the use of the mid-infrared and terahertz region of the electromagnetic spectrum. The book provides an introductory part to each topic so that it can be used in a self-contained way, while references to the literature will allow deeper studies for further research.

Dispersion dynamics are developed from the stable wave packet in wave mechanics. They are used first in a physical treatment of creation and annihilation, and then applied to measurements in high temperature superconductivity. The dynamics require that the negative energy solution to relativity equations implies negative rest mass in the antiparticle. Diracs positive mass for his first order equation is inconsistent with dispersion dynamics. The processing of the ceramic cuprates links the superconductivity not to the isotope effect, as in low temperature superconductors, but to chemical holes in the planar HiTc ceramics. The Hall coefficient is negative in the former case, but positive in the latter -- even though the Lorentz force can act on neither voids nor immobile ionic nuclei. Interpretation of the coefficient is an old anomaly. In fact, whether in metals, in p-type semiconductors or in HiTc ceramics, the carriers are all negatively charged. Dispersion dynamics show that the positive coefficient is a consequence of negative second derivatives in the dispersion of conduction bands in semiconductors, in certain metals and in high temperature superconductors.Existing data from HiTc compounds, especially data from processing, are reinterpreted to show how chemical and physical holes are formed. The holes that are evident in the Hall effect at normal temperatures are readily available to bond with electron pairs at lower temperatures for superconductivity. Wave functions in dispersion dynamics show how the conduction is non-resistive. The book contrasts the two types of superconductivity while uniting the mechanism in them for non-resistive behaviour.

This book describes the state-of-the-art in energy efficient, fault-tolerant embedded systems. It covers the entire product lifecycle of electronic systems design, analysis and testing and includes discussion of both circuit and system-level approaches. Readers will be enabled to meet the conflicting design objectives of energy efficiency and fault-tolerance for reliability, given the up-to-date techniques presented.
