Download Spin-Orbit-Induced Spin Textures of Unoccupied Surface States on Tl/Si(111) Book in PDF, Epub and Kindle
This thesis describes the construction of a rotatable spin-polarized electron source and its use in spin- and angle-resolved inverse photoemission to investigate the unoccupied electron states of Tl/Si(111)-(1x1) with special emphasis on their spin texture. Towards more efficient electronics - with the electron spin as information carrier: This motto is the motivation for numerous studies in solid state physics that deal with electron states whose spin degeneracy is lifted by spin-orbit interaction. This thesis addresses the spin-orbit-induced spin textures in momentum space in the surface electronic structure of a prototypical Rashba-type hybrid system: heavy metal thallium on semiconducting silicon. For Tl/Si(111)-(1x1), the thallium adlayer provides surface states with strong spin-orbit interaction and peculiar spin-orbit-induced spin textures: spin rotations and spin chirality in momentum space for unoccupied surface states with giant spin splittings. Almost completely out-of-plane spin-polarized valleys in the vicinity of the Fermi level are identified. As the valley polarization is oppositely oriented at specific points in momentum space, backscattering should be strongly suppressed in this system.

Download Spin-orbit Coupling Effects in Two-Dimensional Electron and Hole Systems Book in PDF, Epub and Kindle
The first part provides a general introduction to the electronic structure of quasi-two-dimensional systems with a particular focus on group-theoretical methods. The main part of the monograph is devoted to spin-orbit coupling phenomena at zero and nonzero magnetic fields. Throughout the book, the main focus is on a thorough discussion of the physical ideas and a detailed interpretation of the results. Accurate numerical calculations are complemented by simple and transparent analytical models that capture the important physics.

Download Spin-orbit Coupling Induced Phenomena at Metal Surfaces and Interfaces Book in PDF, Epub and Kindle
We develop a first principles approach to calculate the MOKE from the optical conductivity determined by linear response theory in the long wavelength limit applied to the single-particle eigenvalues and wavefunctions obtained by the FLAPW method. We apply this approach to bulk bcc Fe and fcc Co and obtain the conductivity and Kerr spectra that are comparable to experiment and with negligible anisotropy about the magnetization direction. From applications to the CoPtn (n = 1 and 3) alloys and multilayers, we find that the Kerr spectra is very sensitive to structural changes and composition, which is explained by the change of band structures in the different geometries rather than by the correlation between the MOKE and SOC strength. The strong spectra of these systems is mostly attributed to the large SOC strength of Pt. Finally, we carry out MOKE calculations for Fe and Co free standing thin films and find that the surface effects cause a red-shift for the peak at the mid-visible light energies and a reduction of the infrared spectra mainly due to band narrowing and enhanced magnetization, both of which imply better agreement with experiment.

Download Topological Insulators Book in PDF, Epub and Kindle
There are only few discoveries and new technologies in physical sciences that have the potential to dramatically alter and revolutionize our electronic world. Topological insulators are one of them. The present book for the first time provides a full overview and in-depth knowledge about this hot topic in materials science and condensed matter physics. Techniques such as angle-resolved photoemission spectrometry (ARPES), advanced solid-state Nuclear Magnetic Resonance (NMR) or scanning-tunnel microscopy (STM) together with key principles of topological insulators such as spin-locked electronic states, the Dirac point, quantum Hall effects and Majorana fermions are illuminated in individual chapters and are described in a clear and logical form. Written by an international team of experts, many of them directly involved in the very first discovery of topological insulators, the book provides the readers with the knowledge they need to understand the electronic behavior of these unique materials. Being more than a reference work, this book is essential for newcomers and advanced researchers working in the field of topological insulators.
