Available in PDF, EPUB and Kindle. Book excerpt: This review volume presents both basic and applied aspects of diluted magnetic semiconductors (DMS). The term DMS applies generally to semiconductors in which a fraction of its constituent ions are replaced by magnetic ions. This book is only the second to review DMS materials. It presents a detailed treatment of the current state of knowledge of the established properties of DMS in the form of single crystals, quantum wells and superlattices. It also brings together recent work on new DMS materials and presents discussions on a wide range of possible DMS applications.

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.

Available in PDF, EPUB and Kindle. Book excerpt: Growth of dilute magnetic semiconductors GaMnN and AlGaMnN showing ferromagnetic behavior above room temperature was achieved. Two approaches were used for Mn doping. GaMnN films were grown by MOCVD using (EtCp2)Mn as the precursor for in-situ Mn doping, while AlGaMnN samples were grown by post growth solid state Mn diffusion into MOCVD grown AlGaN films. Curie temperatures of the GaMnN films ranged from 270 to above 400K depending on Mn concentration. This dependence of Curie temperature on Mn concentration indicates that the GaMnN films are random solid solutions. Ferromagnetic behavior for these films were observed along c-direction (out of plane orientation) in a Mn concentration range of 0.025-0.25%. The saturation magnetizations ranged between 0.18 and 1.0 emu/cc, fairly high values considering the low levels of Mn doping. SQUID measurements ruled out the possibility of spin-glass and superparamagnetism in these MOCVD grown GaMnN films. Structural characterizations of the GaMnN films were achieved by XRD, SIMS and TEM measurements. XRD and TEM confirmed that the films were single crystal solid solutions without the presence of secondary phases. SIMS revealed that Mn was incorporated homogeneously throughout the GaMnN layer. The samples were highly resistive to be characterized by Hall measurement; however PL measurements showed that the samples were optically active. For the AlGaMnN films, SQUID and VSM measurements on several samples revealed ferromagnetism above room temperature. SQUID measurements on 30%AlN sample determined a Curie temperature of 320K and confirmed the absence of superparamagnetism. SIMS verified the diffusion of Mn into the AlGaN lattice, and XRD showed no sign of secondary phases. However TEM is necessary to rule out the presence of secondary phases. This study showed that the growth of III-Nitride films doped with Mn require special growth conditions to achieve ferromagnetism above room temperature, and the grown films do not have to be.

Book excerpt: ABSTRACT: The utilization of the spin as an additional degree of freedom to electronic transport opens a new field for novel electronic devices combined with magnetic and optical properties. Semiconductors doped with some amount of the magnetic element have been developed as an effective injector of spin-polarized carriers owing to a good electrical conductivity match with semiconductors to be hybridized.
