Book Description
Scanning tunneling microscopy (STM) and its extensions have become revolutionary tools in the fields of physics, materials science, chemistry, and biology. These new microscopies have evolved from their beginnings asresearch aids to their current use as commercial tools in the laboratory and on the factory floor. New wonders continue to unfold as STM delivers atomic scale imaging and electrical characterization of the newly emerging nanometer world. This volume in the METHODS OF EXPERIMENTAL PHYSICS Series describes the basics of scanning tunneling microscopy, provides a fundamental theoretical understanding of the technique and a thorough description of the instrumentation, and examines numerous examples and applications. Written by the pioneers of the field, this volume is an essential handbook for researchers and users of STM, as well as a valuable resource for libraries.

Book Description
Scanning Tunneling Microscopy I provides a unique introduction to a novel and fascinating technique that produces beautiful images of nature on an atomic scale. It is the first of three volumes that together offer a comprehensive treatment of scanning tunneling microscopy, its diverse applications, and its theoretical treatment. In this volume the reader will find a detailed description of the technique itself and of its applications to metals, semiconductors, layered materials, adsorbed molecules and superconductors. In addition to the many representative results reviewed, extensive references to original work will help to make accessible the vast body of knowledge already accumulated in this field.

Book Description
The present work introduces a new concept for magnetic resonance measurements in the GHz regime inside a scanning tunneling microscope. It is based on heterodyne detection in a spin-polarized tunneling barrier. The experimental requirements, including a new method to suppress transmission effects, are explained. Measurements on three model systems which were studied to validate the new technique are presented and compared to simulations.

Book Description
The first part of this dissertation introduces the theoretical background for the Magnetic Force Microscope (MFM), the Spin Polarized Scanning Tunneling Microscope (SP-STM), and the theoretical basis for magnetic domains.The second part addresses issues on the design and construction of a low temperature magnetic force microscope (LT-MFM) and its operation. The third part focuses on the LT-MFM experimental investigation on ternary UMn2Ge2 crystals. The forth part describes the construction and implementation of a low temperature SP-STM system. Scanning probe microscopy (SPM), beginning with the invention of the STM, was first developed to study the electronic properties of different materials, such as imaging high T[subscript c] superconductors. But soon, as the SPM family expanded, some of them developed into powerful techniques to characterize magnetic features. This category includes MFM and SP-STM. The former was widely used for imaging surface magnetic properties from hundreds of micrometers down to the nanometer scale, ideal for imaging magnetic domains. With our homemade LT-MFM system, we studied UMn2Ge2 single crystals, in which both the Uranium and Manganese atoms are magnetic. Flower-like magnetic domain pattern were found at room temperature, and they persisted all the way down to low temperature. Around 150K, Uranium atom ordering was revealed in the form of magnetic domain wall jumps, by partially saturating the sample and warming it up in zero field. In addition, the underlying mechanism of the flower pattern was explained using the domain branching scheme. On the other hand, a Low temperature SP-STM (LT-SP-STM) was designed and constructed, paving the way for spin mapping at the atomic scale thus characterizing magnetic materials with ultra-resolution.

Book Description
The scanning tunnelling microscope (STM) was invented by Binnig and Rohrer and received a Nobel Prize of Physics in 1986. Together with the atomic force microscope (AFM), it provides non-destructive atomic and subatomic resolution on surfaces. Especially, in recent years, internal details of atomic and molecular wavefunctions are observed and mapped with negligible disturbance. Since the publication of its first edition, this book has been the standard reference book and a graduate-level textbook educating several generations of nano-scientists. In Aug. 1992, the co-inventor of STM, Nobelist Heinrich Rohrer recommended: "The Introduction to Scanning tunnelling Microscopy by C.J. Chen provides a good introduction to the field for newcomers and it also contains valuable material and hints for the experts". For the second edition, a 2017 book review published in the Journal of Applied Crystallography said "Introduction to Scanning tunnelling Microscopy is an excellent book that can serve as a standard introduction for everyone that starts working with scanning probe microscopes, and a useful reference book for those more advanced in the field". The third edition is a thoroughly updated and improved version of the recognized "Bible" of the field. Additions to the third edition include: theory, method, results, and interpretations of the non-destructive observation and mapping of atomic and molecular wavefunctions; elementary theory and new verifications of equivalence of chemical bond interaction and tunnelling; scanning tunnelling spectroscopy of high Tc superconductors; imaging of self-assembled organic molecules on the solid-liquid interfaces. Some key derivations are rewritten using mathematics at an undergraduate level to make it pedagogically sound.

Book Description
It has been recognized since the beginning of serious studies in surface science that kinetic processes underpin a whole range of surface phenomena, including, for example, phase transformations and ordering, epitaxial growth, and surface chemical behavior. However, with few exceptions, available techniques have not lent themselves well to obtaining a truly microscopic view of such kinetic processes. Because of its atomic resolution on the one hand, and the achievable wide field of view on the other (i.e., large dynamic range in resolution) scanning tunneling microscopy (STM) does afford this opportunity. In this talk, we briefly review the types of surface kinetics measurements that can be made using STM. It should be pointed out that the use of STM for studies of kinetics is one of the more recent applications of what is itself still a very young field; hence much remains to be accomplished. We have concentrated our investigations on the initial stages of molecular beam epitaxy of Si and Ge on Si(001) and will use this surface in our examples.
