This book was released on 2020-09-07 with total page 109 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reveals unique transport phenomena and functionalities in topological insulators coupled with magnetism and superconductivity. Topological insulators are a recently discovered class of materials that possess a spin-momentum-locked surface state. Their exotic spin texture makes them an exciting platform for investigating emergent phenomena, especially when coupled with magnetism or superconductivity. Focusing on the strong correlation between electricity and magnetism in magnetic topological insulators, the author presents original findings on current-direction-dependent nonreciprocal resistance, current-induced magnetization reversal and chiral edge conduction at the domain wall. In addition, he demonstrates how the coupling between superconductivity and topological surface state leads to substantial nonreciprocal resistance. The author also elucidates the origins of these phenomena and deepens readers’ understanding of the topologically nontrivial electronic state. The book includes several works which are published in top journals and were selected for the President’s Award by the University of Tokyo and for the Ikushi Prize, awarded to distinguished Ph.D. students in Japan.

This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: First-principles density functional theory and non-equilibrium Green function calculations have been conducted to explore the electronic properties of the graphene-like 2D materials. It is found that zigzag boron phosphide nanoribbons (zBPNRs) exhibit non-magnetic direct bandgap semiconducting property and bandgap is about 1 eV. The heterostructure zSiC-BP-SiC nanoribbons are found to display an obvious negative differential resistance (NDR), which are tunable by changing the length of BPNRs. It is also found that for the armchair MoS2/WS2NRs heterostructures, with the number of WS2NR unit cell increasing, the NDR effect can be modulated. Especially for the case of M(edge) with W atoms doping on the edges, it not only exhibits a significant NDR effect but also owns a fast current transport. Therefore, these graphene-like 2D materials may possess potential for the application in logic transistor.
Download or read book Electric Field Control of Magnetization and Electronic Transport in Ferromagnetic Ferroelectric Heterostructures written by Sen Zhang and published by Springer Science & Business Media. This book was released on 2014-04-10 with total page 143 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book mainly focuses on the investigation of the electric-field control of magnetism and spin-dependent transportation based on a Co40Fe40B20(CoFeB)/Pb(Mg1/3Nb2/3)0.7Ti0.3O3(PMN-PT) multiferroic heterostructure. Methods of characterization and analysis of the multiferroic properties with in situ electric fields are induced to detect the direct magnetoelectric (ME) coupling. A switchable and non-volatile electric field control of magnetization in CoFeB/PMN-PT(001) structures is observed at room temperature, and the mechanism of direct coupling between the ferroelectric domain and ferromagnetic film due to the combined action of 109° ferroelastic domain switching in PMN-PT and the absence of magnetocrystalline anisotropy in CoFeB is demonstrated. Moreover, the electric-field control of giant magnetoresistance is achieved in a CoFeB-based spin valve deposited on top of (011) oriented PMN-PT, which offers an avenue for implementing electric-writing and magnetic-reading random access memory at room temperature. Readers will learn the basic properties of multiferroic materials, many useful techniques related to characterizing multiferroics and the interesting ME effect in CoFeB/PMN-PT structures, which is significant for applications.

Available in PDF, EPUB and Kindle. Book excerpt: Ongoing developments in nanofabrication technology and the availability of novel materials have led to the emergence and evolution of new topics for mesoscopic research, including scanning-tunnelling microscopic studies of few-atom metallic clusters, discrete energy level spectroscopy, the prediction of Kondo-type physics in the transport properties of quantum dots, time dependent effects, and the properties of interacting systems, e.g. of Luttinger liquids. The overall understanding of each of these areas is still incomplete; nevertheless, with the foundations laid by studies in the more traditional systems there is no doubt that these new areas will advance mesoscopic electron transport to a new phenomenological level, both experimentally and theoretically. Mesoscopic Electron Transport highlights selected areas in the field, provides a comprehensive review of such systems, and also serves as an introduction to the new and developing areas of mesoscopic electron transport.
Download or read book Electronic Properties of Graphene Heterostructures with Hexagonal Crystals written by John R. Wallbank and published by Springer. This book was released on 2014-06-13 with total page 101 pages. Available in PDF, EPUB and Kindle. Book excerpt: The last decade has witnessed the discovery of, and dramatic progress in understanding the physics of graphene and related two-dimensional materials. The development of methods for manufacturing and aligning high-quality two-dimensional crystals has facilitated the creation of a new generation of materials: the heterostructures of graphene with hexagonal crystals, in which the graphene electrons acquire new, qualitatively different properties. This thesis provides a comprehensive theoretical framework in which to understand these heterostructures, based on the tight binding model, perturbation theory, group theory and the concept of the moire superlattice (all of which are elucidated). It explains how graphene heterostructures provide new opportunities for tailoring band structure, such as creating additional Dirac points or opening band gaps and how they manifest themselves in transport measurements, optical absorption spectra and the fractal Hofstadter spectra. Also considered are the heterostructures of bilayer graphene and resonant tunneling in aligned graphene/insulator/graphene devices.

Available in PDF, EPUB and Kindle. Book excerpt: The dissertation ”Electronic Transport in Noncollinear Magnetic Structures” presents a theoretical investigation into the behavior of electron transport in materials exhibiting non-collinear magnetism. Noncollinear magnetic structures, characterized by complex magnetic ordering and multiple orientations of magnetic moments, have attracted significant interest due to their unique properties and potential applications in spintronics, magnetic memory devices, and quantum computing. This research work focuses on elucidating the fundamental principles that govern electron transport in noncollinear magnetic structures. The dissertation begins with a short review of the theoretical foundations of noncollinear magnetism, including spin-orbit coupling and exchange interactions. This theoretical framework provides the basis for understanding the subsequent theoretical analyses. Utilizing advanced computational methods, the dissertation investigates electron transport properties in noncollinear magnetic materials. The electronic band structures, spin textures, and scattering mechanisms are examined using theoretical and numerical techniques. The calculations enable a detailed exploration of the interplay between magnetism and electron transport phenomena. The dissertation further explores the influence of spin-dependent scattering and spin polarization on electron transport in noncollinear magnetic structures. Theoretical analyses are conducted to understand the impact of external magnetic fields and temperature on the transport properties. The results offer valuable insights into the fundamental mechanisms underlying electron transport in these materials. This work opens up new avenues for the design and optimization of functional materials with tailored electronic properties, advancing the field of noncollinear magnetism and its applications in emerging technologies.

Download or read book High Magnetic Fields In The Physics Of Semiconductors Proceedings Of The 12th International Conference In 2 Volumes written by Gottfried Landwehr and published by World Scientific. This book was released on 1997-04-23 with total page 1108 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains contributions presented at the 12th International Conference on High Magnetic Fields in Semiconductor Physics. In order to give an overview, 37 lecturers not only reviewed the latest results in their field, but also gave a general introduction. The rapid development of semiconductor physics and technology during the last few years has resulted in an extensive application of high magnetic fields in both fundamental and applied research; more than 160 contributed papers were presented as posters.Sixteen years after its discovery, the quantum Hall effect (QHE) is still a subject of high activity. Many new results on the fractional QHE were presented; in addition to 6 invited papers, there were 43 contributions. Another field of high activity is magneto-optics, and 49 posters were presented. Magnetotransport also turned out to be of high interest, and magnetic semiconductors played a prominent role at the conference, too.Without doubt, the availability of superconducting magnets in most laboratories contributed to the growth of semiconductor physics in high magnetic fields. Because not all experiments can be performed in fields up to 10 or 15 teslas, high magnetic field laboratories offering larger fields are indispensable. There were reports from four laboratories on present work going on at these installations.

Download or read book Relativistic Theory of Electron Transport in Magnetic Layers written by Rudolf Sýkora and published by LAP Lambert Academic Publishing. This book was released on 2013 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: The work studies, by means of ab-initio (from-the-first-principles) calculations, effects of the spin-orbit interaction on electron-transport properties of both purely metallic and tunnelling magnetic multilayers. It is shown that even in systems composed of relatively light elements such as nickel and cobalt the interaction may play a crucial role, and not including it in the calculation framework may result in erroneous predictions. The book is written in a self-contained and comprehensive manner. It starts with a detailed explanation of the density-functional theory (DFT), then the particular method of linear muffin-tin orbitals (LMTO) is reviewed. Regarding transport, a form of a Landauer-like formula is derived. Finally, the theory is applied on illustrative systems which show a particularly marked effects of the spin-orbit interaction.
