Solid State Lighting Reliability: Components to Systems begins with an explanation of the major benefits of solid state lighting (SSL) when compared to conventional lighting systems including but not limited to long useful lifetimes of 50,000 (or more) hours and high efficacy. When designing effective devices that take advantage of SSL capabilities the reliability of internal components (optics, drive electronics, controls, thermal design) take on critical importance. As such a detailed discussion of reliability from performance at the device level to sub components is included as well as the integrated systems of SSL modules, lamps and luminaires including various failure modes, reliability testing and reliability performance. A follow-up, Solid State Lighting Reliability Part 2, was published in 2017.

This book focuses on the development of liquid crystal displays (LCDs) and liquid crystal materials (LCs) in Japan. The Committee of Organic Materials Research for Information Sciences of the Japan Society for the Promotion of Science (JSPS) planned the book to document essential LCD innovations and developments since the beginnings of the field-effect LCD technology in 1970. The book illustrates the remarkable effort and progress behind those flat, lightweight, and high-information-content LCDs that have become the indispensable human-machine interface for virtually all electronic devices. In contrast to other publications on this topic, the book illustrates the interdisciplinary character of the LCD technology and its crucial importance for technological progress of the field far beyond displays. It also gives insights into breakthrough innovations not revealed in other publications. Moreover, prospects for the development of LC research toward new fields of applications are provided. In line with its interdisciplinary character, the book targets researchers in basic science as well as engineers and researchers in industry.
This thesis makes a significant contribution to the development of cheaper Si-based Infrared detectors, operating at room temperature. In particular, the work is focused in the integration of the Ti supersaturated Si material into a CMOS Image Sensor route, the technology of choice for imaging nowadays due to its low-cost and high resolution. First, the material is fabricated using ion implantation of Ti atoms at high concentrations. Afterwards, the crystallinity is recovered by means of a pulsed laser process. The material is used to fabricate planar photodiodes, which are later characterized using current-voltage and quantum efficiency measurements. The prototypes showed improved sub-bandgap responsivity up to 0.45 eV at room temperature. The work is further supported by a collaboration with STMicroelectronics, where the supersaturated material was integrated into CMOS-based sensors at industry level. The results show that Ti supersaturated Si is compatible in terms of contamination, process integration and uniformity. The devices showed similar performance to non-implanted devices in the visible region. This fact leaves the door open for further integration of supersaturated materials into CMOS Image Sensors.

This text on the electrical, optical, magnetic, and thermal properties of materials stresses concepts rather than mathematical formalism. Suitable for advanced undergraduates, it is intended for materials and electrical engineers who want to gain a fundamental understanding of alloys, semiconductor devices, lasers, magnetic materials, and so forth. The book is organized to be used in a one-semester course; to that end each section of applications, after the introduction to the fundamentals of electron theory, can be read independently of the others. Many examples from engineering practice serve to provide an understanding of common devices and methods. Among the modern applications covered are: high-temperature superconductors, optoelectronic materials, semiconductor device fabrication, xerography, magneto-optic memories, and amorphous ferromagnetics. The fourth edition has been revised and updated with an emphasis on the applications sections, which now cover devices of the next generation of electronics.

The fact that there are more embedded computers than
general-purpose computers and that we are impacted by hundreds of
them every day is no longer news. What is news is that their
increasing performance requirements, complexity and capabilities
demand a new approach to their design.
This book addresses the piezoresistance in p-type 3C-SiC, which it investigates using experimental characterization and theoretical analysis. The gauge factor, the piezoresistive coefficients in two-terminal and four-terminal resistors, the comparison between single crystalline and nanocrystalline SiC, along with the temperature dependence of the piezoresistive effect in p-type 3C-SiC are also discussed. Silicon carbide (SiC) is an excellent material for electronic devices operating at high temperatures, thanks to its large energy band gap, superior mechanical properties and extreme chemical inertness. Among the numerous polytypes of SiC, the cubic single crystal, which is also well known as 3C-SiC, is the most promising platform for microelectromechanical (MEMS) applications, as it can be epitaxially grown on an Si substrate with diameters of up to several hundred millimeters. This feature makes 3C-SiC compatible with the conventional Si-based micro/nano processing and also cuts down the cost of SiC wafers. The investigation into the piezoresistive effect in 3C-SiC is of significant interest for the development of mechanical transducers such as pressure sensors and strain sensors used for controlling combustion and deep well drilling. Although a number of studies have focused on the piezoresistive effect in n-type 3C-SiC, 4H-SiC and 6H-SiC, comparatively little attention has been paid to piezoresistance in p-type 3C-SiC. In addition, the book investigates the piezoresistive effect of top-down fabricated SiC nanowires, revealing a high degree of sensitivity in nanowires employing an innovative nano strain-amplifier. The large gauge factors of the p-type 3C-SiC at both room temperature and high temperatures found here indicate that this polytype could be suitable for the development of mechanical sensing devices operating in harsh environments with high temperatures.
