This book was released on 2012-12-06 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: Semimagnetic semiconductors (SMSC) and diluted magnetic semiconductors (DMS) have in the past decade attracted considerable attention because they confer many new physical properties on both bulk materials and heterostructures. These new effects are due either to exchange interactions between magnetic moments on magnetic ions, or to exchange interactions between magnetic moments and the spin of the charge carrier. These effects vary with the transition metal (Mn, Fe, Co) or rare earth (Eu, Gd, etc) used and thus provide a range of different situations. The field is very large (zero gap, small gap, wide gap), and the magnetic properties also are very rich (paramagnetic spin glass, antiferromagnetism). These materials are very convenient for studying the magnetism (the magnetism is diluted) or the superlattices (SL) with a continuous change from type II SL to type III SL. This Course attempted to provide a complete overview of the topic. The participants of this summer school held in Erice came from ten countries and were from various backgrounds and included theoreticians, experimentalists, physicists, and chemists. Consequently, an attempt was made to make the Course as thorough as possible, but at the same time attention was devoted to basic principles. The lecturers, drawn from all the groups in the world involved in the field, were asked to be very didactic in their presentation. After two introductory lectures, Dr.

Book excerpt: Spectroscopic techniques are among the most powerful characterization methods used to study semiconductors. This volume presents reviews of a number of major spectroscopic techniques used to investigate bulk and artificially structured semiconductors including: photoluminescence, photo-reflectance, inelastic light scattering, magneto-optics, ultrafast work, piezo-spectroscopy methods, and spectroscopy at extremely low temperatures and high magnetic fields. Emphasis is given to major semiconductor systems, and artificially structured materials such as GaAs, InSb, Hg1-xCdxTe and MBE grown structures based upon GaAs/AlGaAs materials. Both the spectroscopic novice and the expert will benefit from the descriptions and discussions of the methods, principles, and applications relevant to today's semiconductor structures.Key Features* Discusses the latest advances in spectroscopic techniques used to investigate bulk and artificially structured semiconductors* Features detailed review articles which cover basic principles* Highlights specific applications such as the use of laser spectroscopy for the characterization of GaAs quantum well structures

This book was released on 2011 with total page 79 pages. Available in PDF, EPUB and Kindle. Book excerpt: AbstractSpintronics has been one of the most rapidly developing research areas in condensed matter physics. Exploiting the electron's spin degree of freedom is hoped to yield new and novel technological applications. The ability to generate a non-equilibrium spin population, to manipulate the spins, and to be able to detect them have been the most intensely studied subjects in this research area. In this dissertation, spin injection from an Fe (Iron) ferromagnetic spin polarizing contact into two dimensional semiconductor hetero-structures were investigated using a device called a "Spin-LED" also known as a Spin Light Emitting Diode. Due to its high Curie temperature, Fe is a very promising candidate for practical applications at room temperature. This dissertation is comprised of two separate experimental studies outlined as follows.1. We have investigated the Polarization of the Spin LEDs as function of Bias. In addition to the exciton we see a feature called "LV" (Low Voltage) that is bias and temperature dependent. We have compared the Spin life time TS measured for the exciton, LV feature in the device (Spin LED) and for the exciton in the unprocessed InGaAs QW. The LV feature shows polarization in excess of 70% and the polarization changes sign as we increase the magnetic field from B = 0 Tesla to B = 7 Tesla.2. We see intensity oscillations in for the photoluminescence for exciton in the InGaAs QWs. We attribute these oscillations to the Optical Aharonov-Bohm effect. A shift in the oscillations has been observed when the sample relative angle with respect to the magnetic field is changed. These oscillations are present only in the Faraday's geometry and disappear in the Voigt geometry.

This book was released on 2000-06-30 with total page 470 pages. Available in PDF, EPUB and Kindle. Book excerpt: Optical methods for investigating semiconductors and the theoretical description of optical processes have always been an important part of semiconductor physics. Only the emphasis placed on different materials changes with time. Here, a large number of papers are devoted to quantum dots, presenting the theory, spectroscopic investigation and methods of producing such structures. Another major part of the book reflects the growing interest in diluted semiconductors and II-IV nanosystems in general. There are also discussions of the fascinating field of photonic crystals. `Classical' low dimensional systems, such as GsAs/GaAlAs quantum wells and heterostructures, still make up a significant part of the results presented, and they also serve as model systems for new phenomena. New materials are being sought, and new experimental techniques are coming on stream, in particular the combination of different spectroscopic modalities.
