A major current challenge for semiconductor devices is to develop materials for the next generation of optical communication systems and solar power conversion applications. Recently, extensive research has revealed that an introduction of only a few percentages of nitrogen into III-V semiconductor lattice leads to a dramatic reduction of the band gap. This discovery has opened the possibility of using these material systems for applications ranging from lasers to solar cells.

Even as we enter the nanotechnology era, we are now encountering the 50th anniversary of the invention of the IC. Will silicon continue to be the pre-eminent material and will MooreTM's Law continue unabated, albeit in a broader economic venue, in the nanotechnology era? This monograph addresses these issues by a re-examination of the scientific and technological foundations of the micro-electronics era. By better assessing and understanding the past five decades of this era, it is proposed that a firmer foundation can be laid for the research that will ensue and possibly...

Organic semiconductors offer unique characteristics which have prompted the application of organic semiconductors and their devices in physical, chemical, and biological sensors. This book covers this emerging field by discussing both optically- and electrically-based sensor concepts. Novel transducers based on organic light-emitting diodes and organic thin-film transistors, as well as systems-on-a-chip architectures are presented. Functionalization techniques are also outlined.

The most straightforwardmethod to change the surface properties of a ma- rial is to deposit a thin ?lm or coating on it. Hence, it is not surprising that an overwhelming amount of scienti?c and technical papers is published each year on this topic. Sputter deposition is one of the many so-called physical vapour deposition (PVD) techniques. In most cases, sputter deposition uses a magnetically enhanced glow discharge or magnetron discharge to produce the ions which bombard and sputter the cathode material. In the ?rst chapter of this book (Chap. 1), the details of the sputter process are...

The focus of this book is on modeling and simulations used in research on the morphological evolution during film growth. The authors emphasize the detailed mathematical formulation of the problem. The book will enable readers themselves to set up a computational program to investigate specific topics of interest in thin film deposition. It will benefit those working in any discipline that requires an understanding of thin film growth processes.

We presented an approach for the visual discrimination of children (3 5 years old) from adults using stride-based properties of their walking style. Trajectories of marked head and ankle positions for six children and nine adults were used to compute the relative stride and stride frequency for each walker at di?erent speeds. The distinction between child and adult for these features is quite strong and reduces the task of categorization to a linear discrimination test. Using a trained two-class linear perceptron, we were able to achieve a correct classi?- tion rate of 93 95% for our dataset....

Die Neigung des Menschen, kleine Dinge wichtig zu nehmen, hat sehr viel GrofJes hervorgebracht. The human tendency to regard little things as important has produced very many great things. Georg Christoph Lichtenberg (1742-1799) The German physicist and poet Lichtenberg knew nothing about polymer films or nanoparticles. But it is quite likely that he had seen colored glasses with embedded metal nanoparticles made by unidentified Roman glassmakers or so-called ruby glasses created by Johann Kunckel (ca. 1630-1703), a Ger man alchemist. Colored glasses were one of the first...

Atomistic and Continuum Modeling of Nanocrystalline Materials develops a complete and rigorous state-of-the-art analysis of the modeling of the mechanical behavior of nanocrystalline (NC) materials. Among other key topics, the material focuses on the novel techniques used to predict the behavior of nanocrystalline materials. Particular attention is given to recent theoretical and computational frameworks combining atomistic and continuum approaches. Also, the most relevant deformation mechanisms governing the response of nanocrystalline materials are addressed and discussed in correlation...

Historically, quasi-low-dimensional superconductors were considered as the main candidates to observe high-temperature superconductivity. For a disc- sion of the related exotic mechanisms of superconductivity, suggested by W.A. Little and V.L. Ginzburg, see a chapter by D. J erome in this volume. Unf- tunately, high-temperature superconductivity has not been discovered yet in quasi-one-dimensional (Q1D) and quasi-two-dimensional (Q2D) organic ma- rials. Nevertheless, very rich and, in many cases, unique physical properties of their metallic, superconducting, charge- and spin-density-wave...
