This book is the first to give a comprehensive description of the physics and applications of resonant tunneling diodes. The opening chapters of the book set out the basic principles of coherent tunneling theory. The authors describe in detail the effects of impurity scattering, femtosecond dynamics, non-equilibrium distribution, and intrinsic bistabilities. They review the applications of RTDs, such as in high-frequency signal generation and multi-valued data storage, and close the book with a chapter on the new field of resonant tunneling through laterally confined zero-dimensional structures. Covering all the key theoretical and experimental aspects of this active area of research, the book will be of great value to graduate students of quantum transport physics and device engineering, as well as to researchers in both these fields.

This book highlights and investigates novel solid-state luminescent properties of crystals with stimuli-responsive behavior. Several novel molecular designs for controlling crystal structures with photo-physical properties are described, with a special focus on external stimuli-responsive properties. The major goal of the material design concept was to capitalize on the chirality of crystals with stimuli-responsive properties. To allow crystals' chirality to be controlled and modified by means of external stimulation, the axial chirality of biaryl moiety was employed and, interestingly, produced several novel mechano- and vapo-responsive luminescent properties based on crystal-to-crystal or single-crystal-to-single-crystal phase transitions. In addition, the book details how the molecular rotation of luminophores in the solid phase can be used to achieve corresponding thermal-responsive phosphorescence. The reports presented here illustrate how the author has succeeded in controlling structural factors in a bulk environment by using molecular design with linking to photo-physical properties. The content will be of great interest to researchers in the field, and to members of chemical and material science societies.

Caustics are natural phenomena, forming light patterns in rainbows or through drinking glasses, and creating light networks at the bottom of swimming pools. Only in recent years have scientists started to artificially create simple caustics with laser light. However, these realizations have already contributed to progress in advanced imaging, lithography, and micro-manipulation. In this book, Alessandro Zannotti pioneers caustics in many ways, establishing the field of artificial caustic optics. He employs caustic design to customize high-intensity laser light. This is of great relevance for laser-based machining, sensing, microscopy, and secure communication. The author also solves a long standing problem concerning the origin of rogue waves which appear naturally in the sea and can have disastrous consequences. By means of a far-reaching optical analogy, he identifies scattering of caustics in random media as the origin of rogue waves, and shows how nonlinear light-matter interaction increases their probability.

This thesis reports a rare combination of experiment and theory on the role of geometry in materials science. It is built on two significant findings: that curvature can be used to guide crack paths in a predictive way, and that protected topological order can exist in amorphous materials. In each, the underlying geometry controls the elastic behavior of quasi-2D materials, enabling the control of crack propagation in elastic sheets and the control of unidirectional waves traveling at the boundary of metamaterials. The thesis examines the consequences of this geometric control in a range of materials spanning many orders of magnitude in length scale, from amorphous macroscopic networks and elastic continua to nanoscale lattices.

This book presents fabrication approaches that could be adapted for the high-throughput and low-cost manufacturing of the proposed transparent electrode. It proposes and demonstrates a new type of embedded metal-mesh transparent electrode (EMTE) that offers superior electrical, optical, and mechanical properties. The structure of the EMTE allows thick metal mesh to be used (for high conductivity) without sacrificing surface smoothness. In addition, the embedded structure improves the EMTE's mechanical stability under high bending stress, as well as its chemical stability in ambient environments. These design aspects are then shown to be suitable for larger electrode areas, narrower metal-mesh line widths, and a wide range of materials, and can easily be adapted to produce flexible and even stretchable devices. In closing, the book explores the practical applications of EMTEs in flexible bifacial dye-sensitized solar cells and transparent thin-film heaters, demonstrating their outstanding performance.

This book addresses a key technology for digital information processing: Kalman filtering, which is generally considered to be one of the greatest discoveries of the 20th century. It introduces readers to issues concerning various uncertainties in a single plant, and to corresponding solutions based on adaptive estimation. Further, it discusses in detail the issues that arise when Kalman filtering technology is applied in multi-sensor systems and/or multi-agent systems, especially when various sensors are used in systems like intelligent robots, autonomous cars, smart homes, smart buildings, etc., requiring multi-sensor information fusion techniques. Furthermore, when multiple agents (subsystems) interact with one another, it produces coupling uncertainties, a challenging issue that is addressed here with the aid of novel decentralized adaptive filtering techniques.Overall, the book's goal is to provide readers with a comprehensive investigation into the challenging problem of making Kalman filtering work well in the presence of various uncertainties and/or for multiple sensors/components. State-of-art techniques are introduced, together with a wealth of novel findings. As such, it can be a good reference book for researchers whose work involves filtering and applications; yet it can also serve as a postgraduate textbook for students in mathematics, engineering, automation, and related fields.To read this book, only a basic grasp of linear algebra and probability theory is needed, though experience with least squares, navigation, robotics, etc. would definitely be a plus.
