Available in PDF, EPUB and Kindle. Book excerpt: The work discussed in this thesis represents the accumulation of research I performed throughout my doctoral studies. My studies were focused towards two-dimensional electronic transport in semiconductor and perovskite oxide interfaces. Electronic materials with low dimensionality provides experimentalists and theorists with incredible systems to probe physics at non-intuitive levels. Once considered "toy problems," low-dimensional systems, particularly in two dimensions, are now treated as highly relevant, modern electronic materials on the verge of being used in next-generation technology. This thesis entails three main parts, each contributing new knowledge to the field of two-dimensional electronics and condensed matter physics in general. The first part, found in Chapter 3, analyzes short-range scattering effects in two-dimensional GaAs/AlGaAs quantum wells. The effect of aluminum concentration in the material is correlated to the non-monotonic resistance behavior at low temperatures through the short-range disorder potential. By accounting for different electronic scattering mechanisms, temperature-dependent resistance is shown to have a universal behavior, independent of short-range scattering. Chapters 4 transitions from two-dimensional electron gasses in GaAs to quasi-two-dimensional electron gasses in perovskite oxides, specifically gamma-Al2O3/SrTiO3 heterointerfaces. For the first time in that system, a metal-to-insulator transition is measured by backgating the strontium titanate. By measuring the carrier density, it is shown that immobile charge carriers are induced through backgating. Chapter 5 discusses my research on the cubic-to-tetragonal structural phase transition in LaAlO3/SrTiO3 heterointerfaces. By engineering micron-scale devices, I was able to measure the electronic transport properties of tetragonal domain walls below the structural transition temperature. Domain walls are shown to cause anisotropic resistance, which is measurable on small-scale devices. These three studies significantly contribute to the understanding of two-dimensional electronic transport. They elucidate scattering mechanisms at low temperatures, tuning of the metal-to-insulator transition in a perovskite oxide, and electrical transport through grain boundaries. Overall, this work continues to push our knowledge of two-dimensional systems further, toward achieving a complete understanding of low-dimensional transport in complex systems.

Download or read book Strongly Correlated Electrons in Two Dimensions written by Sergey Kravchenko and published by CRC Press. This book was released on 2017-05-25 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: The properties of strongly correlated electrons confined in two dimensions are a forefront area of modern condensed matter physics. In the past two or three decades, strongly correlated electron systems have garnered a great deal of scientific interest due to their unique and often unpredictable behavior. Two of many examples are the metallic state and the metal–insulator transition discovered in 2D semiconductors: phenomena that cannot occur in noninteracting systems. Tremendous efforts have been made, in both theory and experiment, to create an adequate understanding of the situation; however, a consensus has still not been reached. Strongly Correlated Electrons in Two Dimensions compiles and details cutting-edge research in experimental and theoretical physics of strongly correlated electron systems by leading scientists in the field. The book covers recent theoretical work exploring the quantum criticality of Mott and Wigner–Mott transitions, experiments on the metal–insulator transition and related phenomena in clean and dilute systems, the effect of spin and isospin degrees of freedom on low-temperature transport in two dimensions, electron transport near the 2D Mott transition, experimentally observed temperature and magnetic field dependencies of resistivity in silicon-based systems with different levels of disorder, and microscopic theory of the interacting electrons in two dimensions. Edited by Sergey Kravchenko, a prominent experimentalist, this book will appeal to advanced graduate-level students and researchers specializing in condensed matter physics, nanophysics, and low-temperature physics, especially those involved in the science of strong correlations, 2D semiconductors, and conductor–insulator transitions.
Download or read book Spectral Approach to Transport Problems in Two Dimensional Disordered Lattices written by Evdokiya Georgieva Kostadinova and published by Springer. This book was released on 2018-12-11 with total page 107 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book introduces the spectral approach to transport problems in infinite disordered systems characterized by Anderson-type Hamiltonians. The spectral approach determines (with probability one) the existence of extended states for nonzero disorder in infinite lattices of any dimension and geometry. Here, the author focuses on the critical 2D case, where previous numerical and experimental results have shown disagreement with theory. Not being based on scaling theory, the proposed method avoids issues related to boundary conditions and provides an alternative approach to transport problems where interaction with various types of disorder is considered. Beginning with a general overview of Anderson-type transport problems and their relevance to physical systems, it goes on to discuss in more detail the most relevant theoretical, numerical, and experimental developments in this field of research. The mathematical formulation of the innovative spectral approach is introduced together with a physical interpretation and discussion of its applicability to physical systems, followed by a numerical study of delocalization in the 2D disordered honeycomb, triangular, and square lattices. Transport in the 2D honeycomb lattice with substitutional disorder is investigated employing a spectral analysis of the quantum percolation problem. Next, the applicability of the method is extended to the classical regime, with an examination of diffusion of lattice waves in 2D disordered complex plasma crystals, along with discussion of proposed future developments in the study of complex transport problems using spectral theory.

This book was released on 2012-12-06 with total page 471 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Bird of Passage by Rudolf Peierls, we find a paragraph in which he de scribes his Cambridge days in the 1930s: On these [relativistic field theory] problems my main contacts were Dirac, and the younger theoreticians. These included in particular Nevill (now Sir Nevill) Mott, perhaps the friendliest among many kind and friendly people we met then. Professor Kamimura became associated with Sir Rudolf Peierls in the 1950s, when he translated, with his colleagues, Peierls's 1955 textbook, Quantum Theory of Solids, into Japanese. This edition, to which Sir Rudolf himself contributed a preface, benefitted early generations of Japanese solid state physicists. Later in 1974/5, during a sabbatical year spent at the Cavendish Laboratory, Professor Kamimura met and began a long association with Sir Nevill Mott. In particular, they developed ideas for disordered systems. One of the outcomes is a paper coauthored by them on ESR-induced variable range hopping in doped semiconductors. A series of works on disordered systems, together with those on two-dimensional systems, have served as building blocks for Physics of Interacting Electrons in Disordered Systems, in the International Series of Monographs on Physics, coauthored by Aoki and published in 1989 by the Oxford University Press. Soon after Professor Kamimura obtained a D. Sc. in 1959 for the work on the ligand field theory under the supervision ofMasao Kotani, his strong con nections in the international physical community began when he worked at the Bell Telephone Laboratories in 1961/64.

This book was released on 2011-07 with total page 420 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the last few years, there has been extensive research work in the conduction mechanisms in various disordered systems. This book attempts to provide statistical descriptions of the conduction processes in various amorphous systems which are intrinsically characterized by the presence of randomness. This brings out automatically the scaling features existing among the experimentally observed conduction data. Besides, the scaling plot also helps one to identify any common feature between seemingly different systems. The first part of the book discusses the relevant theoretical background related to the conduction processes in disordered systems. The second part concerns about the analysis of the experimental non-linear conduction in three different types of disordered systems. Depending on frequency or temperature, the electrical conduction in these systems may change from being linear to nonlinear when subjected to sufficiently large bias. This book is suitable for Graduate Students, Condensed Matter Researchers and Material Scientists. We have included few sets of problems for the graduate students including some basic problems in many body physics and condensed matter physics

Vilarinho and published by Springer Science & Business Media. This book was released on 2006-06-15 with total page 503 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the characteristic dimensions of electronic devices continue to shrink, the ability to characterize their electronic properties at the nanometer scale has come to be of outstanding importance. In this sense, Scanning Probe Microscopy (SPM) is becoming an indispensable tool, playing a key role in nanoscience and nanotechnology. SPM is opening new opportunities to measure semiconductor electronic properties with unprecedented spatial resolution. SPM is being successfully applied for nanoscale characterization of ferroelectric thin films. In the area of functional molecular materials it is being used as a probe to contact molecular structures in order to characterize their electrical properties, as a manipulator to assemble nanoparticles and nanotubes into simple devices, and as a tool to pattern molecular nanostructures. This book provides in-depth information on new and emerging applications of SPM to the field of materials science, namely in the areas of characterisation, device application and nanofabrication of functional materials. Starting with the general properties of functional materials the authors present an updated overview of the fundamentals of Scanning Probe Techniques and the application of SPM techniques to the characterization of specified functional materials such as piezoelectric and ferroelectric and to the fabrication of some nano electronic devices. Its uniqueness is in the combination of the fundamental nanoscale research with the progress in fabrication of realistic nanodevices. By bringing together the contribution of leading researchers from the materials science and SPM communities, relevant information is conveyed that allows researchers to learn more about the actual developments in SPM applied to functional materials. This book will contribute to the continuous education and development in the field of nanotechnology.
