The manipulation of electric charge in bulk semiconductors and their heterostructures forms the basis of virtually all contemporary electronic and opto-electronic devices. Recent studies of spin-dependent phenomena in semiconductors have now opened the door to technological possibilities that harness the spin of the electron in semiconductor devices. In addition to providing spin-dependent analogies that extend existing electronic devices into the realm of semiconductor "spintronics," the spin degree of freedom also offers prospects for fundamentally new functionality within the quantum domain, ranging from storage to computation. It is anticipated that the spin degree of freedom in semiconductors will play a crucial role in the development of information technologies in the 21st century. This book brings together a team of experts to provide an overview of emerging concepts in this rapidly developing field. The topics range from spin transport and injection in semiconductors and their heterostructures to coherent processes and computation in semiconductor quantum structures and microcavities.

Emerging Memories: Technologies and Trends attempts to provide background and a description of the basic technology, function and properties of emerging as well as discussing potentially suitable applications. This book explores a range of new memory products and technologies. The concept for some of these memories has been around for years. A few completely new. Some involve materials that have been in volume production in other type of devices for some time. Ferro-electrics, for example, have been used in capacitors for more than 30 years. In addition to looking at using known devices and materials in novel ways, there are new technologies being investigated such as DNA memories, light memories, molecular memories, and carbon nanotube memories, as well as the new polymer memories which hold the potential for the significant manufacturing reduction. Emerging Memories: Technologies and Trends is a useful reference for the professional engineer in the semiconductor industry.

In 1987 a major breakthrough occurred in materials science. A new family of materials was discovered that became superconducting above the temperature at which nitrogen gas liquifies, namely, 77 K or –196°C. Within months of the discovery, a wide variety of experimental techniques were brought to bear in order to measure the properties of these materials and to gain an understanding of why they superconduct at such high temperatures. Among the techniques used were electromagnetic absorption in both the normal and the superconducting states. The measurements enabled the determination of a wide variety of properties, and in some instances led to the observation of new effects not seen by other measu- ments, such as the existence of weak-link microwave absorption at low dc magnetic fields. The number of different properties and the degree of detail that can be obtained from magnetic field- and temperature-dependent studies of electromagnetic abso- tion are not widely appreciated. For example, these measurements can provide information on the band gap, critical fields, the H–T irreversibility line, the amount of trapped flux, and even information about the symmetry of the wave function of the Cooper pairs. It is possible to use low dc magnetic field-induced absorption of microwaves with derivative detection to verify the presence of superconductivity in a matter of minutes, and the measurements are often more straightforward than others. For example, they do not require the physical contact with the sample that is necessary when using four-probe resistivity to detect superconductivity.

Physics of Semiconductor Devices is a textbook aimed at college undergraduate and graduate teaching. It covers both basic classic topics such as energy band theory and the gradual-channel model of the MOSFET as well as advanced concepts and devices such as MOSFET short-channel effects, low-dimensional devices and single-electron transistors. As a prerequisite, this text requires mathematics through differential equations and modern physics where students are introduced to quantum mechanics. Concepts are introduced to the reader in a simple way, often using comparisons to everyday-life experiences such as simple fluid mechanics. They are then explained in depth and mathematical developments are fully described. Physics of Semiconductor Devices contains a list of problems that can be used as homework assignments or can be solved in class to exemplify the theory. Many of these problems make use of Matlab and are aimed at illustrating theoretical concepts in a graphical manner. A series of these Matlab problems is based on a simple finite-element solution of semiconductor equations. These yield the exact solution to equations that have no analytical solutions and are usually solved using approximations, such as the depletion approximation. The exact numerical solution can then be graphically compared to the solution using the approximation. The different chapters of Physics of Semiconductor Devices cover the following material: Energy Band Theory. Theory of Electrical Conduction. Generation/Recombination Phenomena. The PN Junction Diode. Metal-semiconductor contacts. JFET and MESFET. The MOS Transistor. The Bipolar Transistor. Heterojunction Devices. Quantum-Effect Devices. Semiconductor Processing.
