Book excerpt: This monograph is intended to give the reader an appreciation of the wealth of phases, elements and inorganic compounds, which crystallize in layer-type or two dimensional structures. Originally this work was planned as a short review article but the large number of phases made it grow out to the size of a book. As is evident from the arrangement of the chapters our point of view was gradually transmuting from geometric to chemical. Moreover, the decision about the compounds that should be discussed was taken only during the course of the work, as is partly evident from the sequence of the references. For chemical or geometrical reason we have included also certain layered chain and molecular structures as well as some layered structures whose layers are linked by hydrogen bonds, thus are in fact three-dimensional. Instead of writing only a review with pseudo-scientific interpretations that later turn out to be wrong anyway we thought it more profitable to include the crystallographic data which are scattered in various original articles and hand books but never in one single volume. We have transcribed many of the data in order to make them correspond with the standard settings of the International Tables for X-Ray Crystallography. The figures are consistent with the data given in the tables. We apologize for errors and hope that their number is at a reasonably low level in spite of the time pressure.

Book excerpt: The development of advanced materials with preselected properties is one of the main goals of materials research. Of especial interest are electronics, high-temperature and supemard materials for various applications, as well as alloys with improved wear, corrosion and mechanical resistance properties. The technical challenge connected with the production of these materials is not only associated with the development of new specialised preparation techniques but also with quality control. The energetic charged particle, electron and photon beams offer the possibility of modifying the properties of the near-surface regions of materials without seriously affecting their bulk, and provide unique analytical tools for testing their qUality. This volume includes most of the lectures and contributions delivered at the NATO-funded Advanced Study Institute "Application of Particle and Laser Beams in Materials Technology", which was held in Kallithea, Chalkidiki, in Northern Greece, from the 8th to the 21st of May, 1994 and attended by 73 participants from 21 countries. The aim of this ASI was to provide to the participants an overview of this rapidly expanding field. Fundamental aspects concerning the interactions and collisions on atomic, nuclear and solid state scale were presented in a didactic way, along with the application of a variety of techniques for the solution of problems ranging from the development of electronics materials to corrosion research and from archaeometry to environmental protection.

Book excerpt: Intermetallic compounds adopt structures that run the gamut of complexity, from simple packings of spheres to structures that require more than three dimensions to fully describe. These diverse intermetallic structures are all influenced by simple chemical factors, such as atomic radius ratios and valence electron concentration, but their role is often poorly understood, hindering the rational design of new intermetallics with potentially useful properties. Previous work in the Fredrickson Group has found that complex structural arrangements can arise from tensions in electron count or atomic packing in a simple parent structure (via the reversed approximation Molecular Orbital and the DFT-Chemical Pressure methods, respectively). Consideration of a single chemical factor, then, enables us to explain why a complex structure forms after synthesis and crystallographic characterization, but it does not provide enough specificity to predict the structural deviation. Making predictions about complex intermetallic structures requires knowing which of several paths a parent structure will take to relieve these issues. In this thesis, we will show that concerted investigation of both atomic size and electron count allows us to navigate a structure's potential configurations and guide our expectations for experimentally observed structures. This concept-called the Frustrated and Allowed Structural Transitions (FAST) principle-says that an allowed structural transition is favorable with respect to both factors, while a frustrated transition has a favorable path in one factor and a constrained path in the other. In each chapter, we present the FAST analysis of the tensions within a parent intermetallic structure that explain and even anticipate the observed experimental structural chemistry. We begin in Chapter 2 with the polymorphism of PtGa2, in which the electronics drive the formation of a complex tetragonal superstructure of the fluorite type while atomic packing enables the stabilization of the electronicallydisfavored cubic form via the incorporation of Pt interstitials. Next, in Chapter 3, we use the FAST analysis in a more predictive way to anticipate complexity in IrSi, which proves to be an incommensurately modulated perturbation of the MnP type. The major form of the modulations (Ir-Ir bonding along directions of negative CP) solves the electronic issues of the MnP type, while the tendency of Ir bonds to form as trimers arises from atomic packing issues between the Ir and Si sublattices. Chapter 4 focuses on the temperature-dependent structural variations of PdBi, where the room temperature polymorph is driven to form by the electron counting of the phase and the high temperature, incommensurate polymorph is favored by entropy and vibrational freedom seen in the parent structure's CP scheme. Finally, in Chapter 5, we use the FAST principle to investigate the CP-driven, electronically-guided structural transition away from the BaAl4 type leading to the incommensurately modulated compound, Dy(Cu0.18Ga0.82)3.71(1). In this case, the modulations lead to block-like incorporation of dumbbell/single atom substitutions that shrink the too-large coordination environments around the Dy atoms, while also balancing the number of substitutions and the amount of Cu incorporated, as both effects lower the electron count of the phase. The work of this thesis establishes the FAST principle as a guideline for understanding complex structural chemistry in intermetallics, laying the groundwork for a predictive chemical framework. As the FAST principle is further refined, we hope to incorporate more chemical factors, such as electronegativity, into the analysis, as well as develop rules for how CP schemes dictate structural chemistry.
