Book excerpt: Im Rahmen der vorliegenden Arbeit ist eine Technologie zur Sputterdeposition ferromagnetischer dünner Schichten aufgebaut worden. Nanostrukturierte ferromagnetische Elektroden, die in Experimenten zum spinpolarisierten Transport eingesetzt werden, wurden präpariert und hinsichtlich ihrer elektrischen und magnetischen Eigenschaften charakterisiert. Im ersten Kapitel werden die Grundlagen der Sputterdeposition und des Sputterätzens erklärt sowie das während dieser Arbeit aufgebaute System beschrieben. Die verwendeten Prozesse wurden mit Hilfe statistischer Methoden charakterisiert. Dabei ist der Einfluss der Argon-Ionenenergie und des Prozessdrucks sowohl auf die Depositions- und Ätzraten als auch auf die Rauhigkeiten der Schichten und Substrate systematisch untersucht worden. Erste Ergebnisse bezüglich der Sputterdeposition der ternären Heusler-Legierung Ni2MnIn werden gezeigt. Dabei wird zusätzlich die Abhängigkeit der Filmstöchiometrie von den Prozessparametern untersucht. Das zweite Kapitel behandelt die Charakterisierung gesputterter ferromagnetischer dünner Schichten und Nanostrukturen. Mit Magnetkraftmikroskopie in äußeren Magnetfeldern und dem magnetooptischen Kerr-Effekt wurden die Formanisotropie und die Kristallanisotropie gesputterter Permalloy (Ni80Fe20)-Elektroden und homogener Schichten untersucht. Der anisotrope Magnetowiderstand wurde an Nanodrähten aus Permalloy und Nickel mit Hilfe von Transportmessungen in äußeren Magnetfeldern untersucht.Das dritte Kapitel behandelt Ferromagnet/Supraleiter-Hybridsysteme. Theoretische Konzepte werden vorgestellt, und die Ergebnisse für elektronenstrahllithografisch definierte Kontakte werden diskutiert. Für Punktkontakte ist während dieser Arbeit ein neues Mess- und Auswertesystem entwickelt worden. Aus den damit gemessenen Transportdaten wurde die Spinpolarisation für verschiedene Materialien bestimmt.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: From the Introduction: Nanotechnology and its underpinning sciences are progressing with unprecedented rapidity. With technical advances in a variety of nanoscale fabrication and manipulation technologies, the whole topical area is maturing into a vibrant field that is generating new scientific research and a burgeoning range of commercial applications, with an annual market already at the trillion dollar threshold. The means of fabricating and controlling matter on the nanoscale afford striking and unprecedented opportunities to exploit a variety of exotic phenomena such as quantum, nanophotonic and nanoelectromechanical effects. Moreover, researchers are elucidating new perspectives on the electronic and optical properties of matter because of the way that nanoscale materials bridge the disparate theories describing molecules and bulk matter. Surface phenomena also gain a greatly increased significance; even the well-known link between chemical reactivity and surface-to-volume ratio becomes a major determinant of physical properties, when it operates over nanoscale dimensions. Against this background, this comprehensive work is designed to address the need for a dynamic, authoritative and readily accessible source of information, capturing the full breadth of the subject. Its six volumes, covering a broad spectrum of disciplines including material sciences, chemistry, physics and life sciences, have been written and edited by an outstanding team of international experts. Addressing an extensive, cross-disciplinary audience, each chapter aims to cover key developments in a scholarly, readable and critical style, providing an indispensible first point of entry to the literature for scientists and technologists from interdisciplinary fields. The work focuses on the major classes of nanomaterials in terms of their synthesis, structure and applications, reviewing nanomaterials and their respective technologies in well-structured and comprehensive articles with extensive cross-references. It has been a constant surprise and delight to have found, amongst the rapidly escalating number who work in nanoscience and technology, so many highly esteemed authors willing to contribute. Sharing our anticipation of a major addition to the literature, they have also captured the excitement of the field itself in each carefully crafted chapter. Along with our painstaking and meticulous volume editors, full credit for the success of this enterprise must go to these individuals, together with our thanks for (largely) adhering to the given deadlines. Lastly, we record our sincere thanks and appreciation for the skills and professionalism of the numerous Elsevier staff who have been involved in this project, notably Fiona Geraghty, Megan Palmer and Greg Harris, and especially Donna De Weerd-Wilson who has steered it through from its inception. We have greatly enjoyed working with them all, as we have with each other.

Available in PDF, EPUB and Kindle. Book excerpt: Moore's Law predicts that the degree of microprocessor integration of circuits would double every 18 months in DRAM. Although the scaling of microelectronic circuit elements still follows Moore's Law, the unit density of power consumption becomes unacceptable. Therefore, on one hand, people develop continuously the microelectronic technology. On the other, people consider the developing road after Moore's rule is broken. This book introduces theories and experiments of quantum transport and intends to provide foundations of semiconductor micro- and nano electronics for after the Moore age.

Available in PDF, EPUB and Kindle. Book excerpt: Semiconductors are at the heart of modern living. Almost everything we do, be it work, travel, communication, or entertainment, all depend on some feature of semiconductor technology. Comprehensive Semiconductor Science and Technology, Six Volume Set captures the breadth of this important field, and presents it in a single source to the large audience who study, make, and exploit semiconductors. Previous attempts at this achievement have been abbreviated, and have omitted important topics. Written and Edited by a truly international team of experts, this work delivers an objective yet cohesive global review of the semiconductor world. The work is divided into three sections. The first section is concerned with the fundamental physics of semiconductors, showing how the electronic features and the lattice dynamics change drastically when systems vary from bulk to a low-dimensional structure and further to a nanometer size. Throughout this section there is an emphasis on the full understanding of the underlying physics. The second section deals largely with the transformation of the conceptual framework of solid state physics into devices and systems which require the growth of extremely high purity, nearly defect-free bulk and epitaxial materials. The last section is devoted to exploitation of the knowledge described in the previous sections to highlight the spectrum of devices we see all around us. Provides a comprehensive global picture of the semiconductor world Each of the work's three sections presents a complete description of one aspect of the whole Written and Edited by a truly international team of experts
