This booklet is the 1st to increase a unified gauge thought of condensed subject structures ruled through vortices or defects and their long-range interactions. Gauge fields give you the in basic terms technique of describing those interactions when it comes to neighborhood fields, rendering them obtainable to straightforward box theoretic thoughts. really vital examples, superfluid platforms and crystals, are handled in nice aspect. the idea is built in shut touch with actual phenomena and evolves evidently from traditional descriptions of the platforms. as well as gauge fields, the booklet introduces the $64000 new proposal of illness fields for ensembles of line-like defects. The mixed box idea makes it possible for a brand new figuring out of the real part transitions superfluid ‘normal and reliable’ liquid. except the above, the publication provides the overall differential geometry of defects in areas with curvature and torsion and establishes touch with the fashionable concept of gravity with torsion. This publication is written for condensed topic physicists and box theorists. it may be used as a textbook for a second-year graduate path or as supplementary studying for classes within the components of condensed topic and reliable nation physics, statistical mechanics, and box conception.

In contemporary years, ever extra digital units have began to make the most the benefits of natural semiconductors. The paintings pronounced during this thesis makes a speciality of interpreting theoretically the strength point alignment of alternative metal/organic interfaces, essential to tailor units with solid functionality. conventional tools in line with density useful idea (DFT), usually are not applicable for reading them simply because they underestimate the natural power hole and fail to properly describe the van der Waals forces.

Since the dimensions of those structures prohibits using extra exact equipment, corrections to these DFT drawbacks are fascinating. during this paintings a mix of a typical DFT calculation with the inclusion of the charging strength (U) of the molecule, calculated from first ideas, is gifted. concerning the dispersion forces, wrong lengthy variety interplay is substituted by way of a van der Waals strength. With those corrections, the C60, benzene, pentacene, TTF and TCNQ/Au(111) interfaces are analyzed, either for unmarried molecules and for a monolayer. the consequences validate the brought about density of interface states model.

Tin (Sn) whiskers are electrically conductive, unmarried crystal eruptions that develop from Sn movie surfaces. Their excessive element ratio offers reliability difficulties for the electronics as a result of bridging and steel arcing, resulting in malfunctions and catastrophic mess ups in lots of digital platforms (including satellite tv for pc and safeguard sectors). because of laws within the ecu, Japan, and the united states, mandating a steady shift from lead (Pb)-based to lead-free solders and board finishes, there was a reemergence of Sn whiskers. carrying on with studies of Sn whisker brought about mess ups coupled with the shortcoming of an industry-accepted knowing of whisker development and/or attempt the right way to determine whisker companies items has made pure/high Sn substitutes a dicy proposition in excessive reliability platforms.

This thesis is designed to explain and keep an eye on the basic mechanisms that govern whisker formation. The study specializes in reproducible "laboratory" created whiskers less than quite a few carefully managed environmental components similar to movie thickness, movie rigidity, substrate fabric, fuel atmosphere, and humidity publicity, that are identified to play an important function in whisker creation. the final word query of the way to abate and/or hinder whisker progress can be addressed and exhibits that whisker prevention is feasible through demanding steel capping motion pictures, that are impenetrable through whiskers.

Section transitions within which crystalline solids suffer structural adjustments current an enticing challenge within the interaction among the crystal constitution and the ordering procedure. this article, meant for readers with a few previous wisdom of condensed-matter physics, emphasizes the elemental physics in the back of such spontaneous structural alterations in crystals. beginning with the appropriate thermodynamic rules, the booklet discusses the character of order variables and their collective movement in a crystal lattice; in a structural part transition a singularity in one of these collective mode is liable for the lattice instability, as published through gentle phonons. This mechanism is similar to the interaction of a charge-density wave and a periodically deformed lattice in low-dimensional conductors. The textual content additionally describes experimental equipment for modulated crystal buildings and offers examples of structural adjustments in consultant structures. The booklet is split into components. the 1st, theoretical, half contains such issues as: the Landau concept of part transitions; facts, correlations and the mean-field approximation; pseudospins and their collective modes; gentle lattice modes and pseudospin condensates; lattice imperfections and their function within the part transitions of actual crystals. the second one half discusses experimental reports of modulated crystals utilizing x-ray diffraction, neutron inelastic scattering, mild scattering, dielectric measurements, and magnetic resonance spectroscopy.
