Описание:
This book is an introduction to a rapidly developing field of modern theoretical physics - the theory of quantum transport at nanoscale. The theoretical methods considered in the book are in the basis of our understanding of charge, spin and heat transport in nanostructures and nanostructured materials and are widely used in nanoelectronics, molecular electronics, spin-dependent electronics (spintronics) and bio-electronics. The book is based on lectures for graduate and post-graduate students at the University of Regensburg and the Technische Universitat Dresden (TU Dresden).
The first part is devoted to the basic concepts of quantum transport: Landauer-Buttiker method and matrix Green function formalism for coherent transport, Tunneling (Transfer) Hamiltonian and master equation methods for tunneling, Coulomb blockade, vibrons and polarons.
The results in this part are obtained as possible without sophisticated techniques, such as nonequilibrium Green functions, which are considered in detail in the second part.
A general introduction into the nonequilibrium Green function theory is given.
The approach based on the equation-of-motion technique, as well as more sophisticated one based on the Dyson-Keldysh diagrammatic technique are presented. The main attention is paid to the theoretical methods able to describe the nonequilibrium (at finite voltage) electron transport through interacting nanosystems, specifically the correlation effects due to electron-electron and electron-vibron interactions.
Описание: This thesis addresses elementary dislocation processes occurring in single-crystalline alloys based on Fe-Al, and investigates correspondences between dislocation distribution inside crystals characterized by transmission electron microscopy (TEM) and surface patterns observed using atomic force microscopy (AFM). Fe-Al alloys with different degrees of ordering were prepared and deformed in compression at ambient temperature in-situ inside the AFM device. The evolution of slip line structures was captured in the sequences of AFM images and wavy slip bands, while cross slip at the tip of the slip band and homogeneous fine slip lines were also identified. Further, the thesis develops a technique for constructing 3D representations of dislocations observed by TEM without the prohibitive difficulties of tomography, and creates 3D models of dislocation structures. Generally speaking, the thesis finds good agreement between AFM and TEM observations, confirming the value of AFM as a relevant tool for studying dislocations.

Описание:
This thesis presents a method for reliably and robustly producing samples of amyloid-? (A?) by capturing them at various stages of aggregation, as well as the results of subsequent imaging with various atomic force microscopy (AFM) methods, all of which add value to the data gathered by collecting information on the peptide’s nanomechanical, elastic, thermal or spectroscopical properties.
Amyloid-? (A?) undergoes a hierarchy of aggregation following a structural transition, making it an ideal subject of study using scanning probe microscopy (SPM), dynamic light scattering (DLS) and other physical techniques. By imaging samples of A? with Ultrasonic Force Microscopy, a detailed substructure to the morphology is revealed, which correlates well with the most advanced cryo-EM work. Early stage work in the area of thermal and spectroscopical AFM is also presented, and indicates the promise these techniques may hold for imaging sensitive and complex biological materials. This thesis demonstrates that physical techniques can be highly complementary when studying the aggregation of amyloid peptides, and allow the detection of subtle differences in their aggregation processes.
