Covers fundamental theoretical aspects of condensed matter physics, with cross-linking and structuring to provide grounding in the theoretical aspects of quantum mechanics, mechanics, electrodynamics, relativity, statistical mechanics, and elementary particles that form the core physics background for the field. These core areas form the background for coverage of such areas as crystallography, transport phenomena, various theoretical models (electronic, band structure, materials property models, etc.), and physical properties of materials (electrical, magnetic, optical, thermal, etc). Coverage of experimental techniques will include, among others, the full range of scattering, microscopy, and spectroscopy techniques. Other entries cover a range of materials processing (solidification, crystal growth, molecular beam epitaxy, sputtering, sintering, etc.) and include coverage of key materials systems (macromolecules, nanostructures, polymers, ceramics, and alloys). Special materials systems that have had and continue to have a major impact on society such as semiconductors, laser materials, and superconductors are covered. The encyclopedia also includes a wide range of applied topics, device-oriented topics, developments in biomaterials, soft condensed matter, complex fluids, etc.
