Magnetoelectronics


Book Description

The arrival of the 'information age' took most people by surprise - including scientists and technologists. Today, research on better, smaller, and faster ways to store and transfer information continues to grow, and growing fast within this scope is the field of magnetoelectronics. With its possibilities as a magnetic storage technology capable of overcoming the vulnerabilities of CMOS (complementary metal on oxide semiconductor), magnetoelectronics promises to be an important installation in the information era.

Magnetoelectronics and Magnetic Materials - Novel Phenomena and Advanced Characterization: Volume 746


Book Description

This book combines the proceedings of Symposium Q, Magnetoelectronics-Novel Magnetic Phenomena in Nanostructures, and Symposium R, Advanced Characterization of Artificially Structured Magnetic Materials, both from the 2002 MRS Fall Meeting in Boston. The common focus is on artificially engineered nanostructured magnetic systems. The two symposia address new phenomena in magnetoelectronic applications, their preparation, and advanced methodology for characterization. Interest in nanomagnetism has been catalyzed by advances in two fields of research. 1) Advances in materials synthesis of structures whose length scales transcend magnetic length scales and open the possibility for creating materials with new magnetic properties. Such structures include interfaces, superlattices, tunneling devices, nanostructures, and single-molecule magnets. 2) Advances in sample characterization techniques for nano-magnetism which allow detailed exploration of structure-property relationships in nanostructured magnetic systems. The volume highlights current trends in both fields and offers an outlook for further advances and new capabilities.







Spin Electronics


Book Description

The history of scientific research and technological development is replete with examples of breakthroughs that have advanced the frontiers of knowledge, but seldom does it record events that constitute paradigm shifts in broad areas of intellectual pursuit. One notable exception, however, is that of spin electronics (also called spintronics, magnetoelectronics or magnetronics), wherein information is carried by electron spin in addition to, or in place of, electron charge. It is now well established in scientific and engineering communities that Moore's Law, having been an excellent predictor of integrated circuit density and computer performance since the 1970s, now faces great challenges as the scale of electronic devices has been reduced to the level where quantum effects become significant factors in device operation. Electron spin is one such effect that offers the opportunity to continue the gains predicted by Moore's Law, by taking advantage of the confluence of magnetics and semiconductor electronics in the newly emerging discipline of spin electronics. From a fundamental viewpoine, spin-polarization transport in a material occurs when there is an imbalance of spin populations at the Fermi energy. In ferromagnetic metals this imbalance results from a shift in the energy states available to spin-up and spin-down electrons. In practical applications, a ferromagnetic metal may be used as a source of spin-polarized electronics to be injected into a semiconductor, a superconductor or a normal metal, or to tunnel through an insulating barrier.




Advanced Semiconducting Materials and Devices


Book Description

This book presents the latest developments in semiconducting materials and devices, providing up-to-date information on the science, processes, and applications in the field. A wide range of topics are covered, including optoelectronic devices, metal–semiconductor junctions, heterojunctions, MISFETs, LEDs, semiconductor lasers, photodiodes, switching diodes, tunnel diodes, Gunn diodes, solar cells, varactor diodes, IMPATT diodes, and advanced semiconductors. Detailed attention is paid to advanced and futuristic materials. In addition, clear explanations are provided of, for example, electron theories, high-field effects, the Hall effect, transit-time effects, drift and diffusion, breakdown mechanisms, equilibrium and transient conditions, switching, and biasing. The book is designed to meet the needs of undergraduate engineering students and will also be very useful for postgraduate students; it will assist in preparation for examinations at colleges and universities and for other examinations in engineering. Practice questions are therefore presented in both essay and multiple choice format, and many solved examples and unsolved problems are included.
