Conducting and semiconducting (conjugated) polymers have a unique set of properties, combining the electronic properties of metals and semiconductors with the processing advantages and mechanical properties of polymers. Now, thirty-five years after their discovery, metallic conducting polymers have been demonstrated in the laboratory to have electrical conductivities approaching that of copper, and mechanical strengths exceeding that of steel, a remarkable achievement. A wide variety of electr...

This PhD thesis reports on investigations of several oxide-based materials using advanced infrared and Raman spectroscopy techniques and in combination with external stimuli such as high magnetic or electric field, sptial confinement in thin film heterostructures and the radiation with UV light. This leads to new results in the fields of superconductivity, electronic polarization states and nanoscale phenomena. Among these, the observation of anomalous polar moments is of great relevance for un...

This book presents the proceedings of the 2nd Karl Schwarzschild Meeting on Gravitational Physics, focused on the general theme of black holes, gravity and information.Specialists in the field of black hole physics and rising young researchers present the latest findings on the broad topic of black holes, gravity, and information, highlighting its applications to astrophysics, cosmology, particle physics, and strongly correlated systems.

One of the most exciting developments in modern physics has been the discovery of the new class of oxide materials with high superconducting transition temperature. Systems with Tc well above liquid nitrogen temperature are already a reality and higher Tc's are anticipated. Indeed, the idea of a room-temperature superconductor, which just a short time ago was considered science fiction, appears to be a distinctly possible outcome of materials research. To address the need to train students and s...

The mBot robotics platform is a hugely popular kit because of the quality of components and price. With hundreds of thousands of these kits out there in homes, schools and makerspaces, there is much untapped potential. Getting Started with mBots is for non-technical parents, kids and teachers who want to start with a robust robotics platform and then take it to the next level. The heart of the mBot, the mCore is a powerful Arduino based microcontroller that can do many things without soldering o...

Provides information on all chemical, physical and material aspects of this class of cuprates, and covers their applications. This work provides data on the chemistry, solid-state chemistry, handling and safety requirements of thallium.

This volume has been divided into four parts. Part 1 deals with material for optoelectronics, part 2 covers semiconductor processing and characterization, part 3 describes IR devices and systems while part 4 describes other devices. The volume is an overview of recent advances in semiconductor-based optoelectronic devices, and systems both for civil and defence applications. Evolution of photocathodes for image intensifiers and advancement in IR detector technology leading to development of comp...

Today, it is difficult to imagine all spheres of human activity without personal computers, solid-state electronic devices, micro- and nanoelectronics, photoconverters, and mobile communication devices. The basic material of modern electronics and for all of these industries is semiconductor silicon. Its properties and applications are determined by defects in its crystal structure. However, until now, there has been no complete and reliable description of the creation and transformation of such...

Semiconductors have become one of the most important materials in our current world. They have allowed the information era to develop, enabling the creation of laptops, superfast computers, smartphones, tablets and other electronic devices. According to Moore's law, these materials have to continue addressing the challenges of miniaturization of electronics, by increasing the quality of the materials and the efficiency of the devices. In addition, they are also very present in energy solutions...

The occurrence of superconductivity among the d- and f-band metals remains one of the unsolved problems of physics. The first Rochester conference on this subject in October 1971 brought together approximately 100 experimentalists and theorists, and that conference was considered successful; the published proceedings well-represented the current research at that time and has served as a "handbook" to many. In the four and one half years since the first conference, impressive progress has been ma...

Advances in the synthesis of new materials with often complex, nano-scaled structures require increasingly sophisticated experimental techniques that can probe the electronic states, the atomic magnetic moments and the magnetic microstructures responsible for the properties of these materials. At the same time, progress in synchrotron radiation techniques has ensured that these light sources remain a key tool of investigation, e.g. synchrotron radiation sources of the third generation are able...

A collection of articles on different approaches to the investigation of surface effects on nanosized magnetic materials, with special emphasis on magnetic nanoparticles. The book provides an overview of progress in the field through recent results.

This thesis introduces readers to the type II superstring theories in the AdS5xS5 and AdS4xCP3 backgrounds. Each chapter exemplifies a different computational approach to measuring observables (conformal dimensions of single-trace operators and expectation values of Wilson loop operators) relevant for two supersymmetric theories: the N=4 super Yang-Mills theory and the N=6 Chern-Simons-matter (ABJM) theory. Perturbative techniques have traditionally been used to make quantitative predictions in...
