New materials design with tunable physical properties has been the dream of many. Well-ordered nanometer-scale materials with 3-dimensional structural order could interact with electronic, magnetic and vibrational degrees of freedom of materials to engineer new properties into well developed semiconductor platforms such as silicon and germanium. The synthetic realization of such structures, which we define as metalattices with periodicity from 1 60 nm highlights the possibility of continuous tuning of properties. Ordered, electrically continuous 3D structural modulations of quantum confinement and interfacial physics could lead to new physical phenomena with new electrical, thermal, magnetic and acoustic responses.This dissertation focus on the synthesis of electronic metalattice structures and other functional materials using high pressure confined chemical vapor deposition (HPcCVD). The synthetic route presented here allows for control over metalattices periodicity, size, symmetry, chemical composition, topology and surface chemistries. The strategy used to fabricate metalattices is to deposit semiconductors such as silicon, germanium and zinc selenide into the pores of nano-templates using HPcCVD. High pressure (up to 70 MPa), allows for void free infiltration of high quality electronic grade materials into nano-pores. A series of templates, including silica colloidal crystals of different sizes, zeolites, mesoporous silica and metal-organic frameworks were examined for tuning periodicities, symmetries and sizes of metalattices. The first silicon and germanium metalattices with 14 nm, 30 nm and 60 nm were made possible with HPcCVD infiltration. A variety of characterization techniques, including Raman spectroscopy, scanning electron microscopy, transmission electron microscopy and x-ray diffraction were used to assess the as deposited materials quality. Post processing methods were developed to remove the nano-template and prepared the sample for advanced characterization and to increase the crystallinity of the synthesized metalattices.

The Second International Conference on Phonon Scattering in Solids was held at the University of Nottingham from August 27th - 30th 1975. It was attended by 192 delegates from 24 countries who were accompanied by 43 members of their families. Eleven invited papers were read and 96 contributed papers; the contributed papers were in two parallel sessions. The Conference included the topics of the two International Conferences held in France in 1972, in Paris and at Ste Maxime. The Conference brought together workers concerned with many aspects of phonon scattering in solids and liquid helium. Some of the work reported were studies of the intrinsic properties of diel ectric materials such as the effects of anharmonicity, dispersion and anisotropy on phonon propagation and the conditions for the existence of zero sound and second sound modes. Work was also pres ented on various aspects of phonon interaction with free electrons in metals and semiconductors. A substantial part of the Conference was devoted to phonon spectroscopy - investigations of the energy levels of ions or neutral impurities by observing the resonant absorp tion or scattering of phonons. The materials being studied include paramagnetic and parae1ectric solids, amorphous systems in which the 'impurities' appear to be intrinsic, and semiconductors. Work was reported on the use of phonons to observe phase transitions; in some cases the cooperative phase also arises through strong spin phonon coupling. One of the intriguing unsolved problems discussed in detail at the Conference is the Kapitza conductance problem.

Phononic crystals are artificial periodic structures that can alter efficiently the flow of sound, acoustic waves, or elastic waves. They were introduced about twenty years ago and have gained increasing interest since then, both because of their amazing physical properties and because of their potential applications. The topic of phononic crystals stands as the cross-road of physics (condensed matter physics, wave propagation in inhomogeneous and periodic media) and engineering (acoustics, ultrasonics, mechanical engineering, electrical engineering). Phononic crystals cover a wide range of scales, from meter-size periodic structures for sound in air to nanometer-size structures for information processing or thermal phonon control in integrated circuits. Phononic crystals have a definite relation with the topic of photonic crystals in optics. The marriage of phononic and photonic crystals also provides a promising structural basis for enhanced sound and light interaction. As the topic is getting popular, it is nowadays presented and discussed at various international conferences. After the first ten years during which the topic has remained mainly theoretical with a few proof-of-concept demonstrations in the literature, the evolution has been towards applications, instrumentation, and novel designs. The physical explanations for various effects are now well understood and efficient numerical methods and analysis tools have been developed. The book contains a comprehensive set of finite element model (FEM) scripts for solving basic phononic crystal problems. The scripts are short, easy to read, and efficient, allowing the reader to generate for him(her)self band structures for 2D and 3D phononic crystals, to compute Bloch waves, waveguide and cavity modes, and more.

The merging of metasurface and holography brings about unprecedented opportunities for versatile manipulation of light in terms of both far-field wavefront and near-field profile. In this book, a brief evolving history from surface plasmon polariton holography to metamaterial holography and finally to metasurface holography is introduced at first. Basic physical mechanisms that govern the phase modulation rules behind metasurface holography design are discussed later. Next, extended functionalities such as arbitrary polarization holography, vectorial holography, full-color holography, and hybrid holography achieved in the metasurface platform are presented. Surface wave and metagrating holography that bridges the on-chip surface wave and free-space wave is also introduced. In the end, we envisage practical applications of high-fidelity 3D holographic display, high-secure encryption, and high capacity digital encoding and also indicate remaining challenges based on metasurface holography.
