Goals and Current Research

The goals of the Basic Energy Sciences (BES) Materials Sciences and Engineering (MS&E) Program at Sandia National Laboratories/New Mexico (SNL/NM) are to:

·    Conduct forefront, interdisciplinary research that supports DOE's Office of Science and BES missions.

·    Establish the "state-of-the-art" in selected areas of materials sciences.

·    Create a research environment that stimulates innovation and attracts and retains outstanding scientists.

·    Increase ties to universities, industries and other National Laboratories.

·    Take advantage of a wide range of large, capital-intensive facilities.

The program has the central theme of Scientifically Tailored Materials. The major objective of this program is to combine Sandia's experimental and theoretical expertise and capabilities in the areas of solid state sciences, nanosciences, advanced atomic-level diagnostics and materials synthesis and processing science to understand physical and chemical phenomena in materials and to produce new classes of tailored materials as well as to enhance the properties of existing materials.

Funding for the Program comes from the Materials and Engineering Physics, Condensed Matter Physics and Materials Chemistry areas of BES/DMS&E. The current research projects under each area are as follows:

Materials and Engineering Physics

·    Physics and Chemistry of Ceramics

·    Theory of Microstructures and Ensemble Controlled Deformation

·    Atomic-Level Science of Adhesion and Interfacial Wetting

·    Localized Corrosion Initiation at Nanoengineered Defects in Passive Films

·    Energetic Particle Synthesis and the Science of Materials

·    Advanced Growth Techniques and the Science of Epitaxy

·    Artificially-Structured Semiconductors

·    Field-Structured Anisotropic Composites and Complex Cooperative Phenomena in Disordered Ferroelectrics and Dielectrics

·    Long-Range Particle Interactions and Collective Phenomena in Plasma Crystals

·    Active Assembly of Dynamic and Adaptable MaterialsCondensed Matter Physics

·    Physics of Nanostructured Semiconductors

·    Atomistic Basis for Surface Nanostructure Formation

·    The Science of Electronic and Optical Interactions Between Coupled Nanostructures

·    The Science of Heteroepitaxial Structural Evolution

·    Synthesis and Processing of Nanoclusters for Energy Applications

·    Cooperative Phenomena in Molecular Nanocomposites

·    Dipolar Nanocomposites

Considerable synergism exists among the various projects in the program, and most of them share a number of common themes based on either the science or the use of common synthesis and processing approaches. These themes are: Nanoscale Science of Materials, Epitaxial Growth, Surfaces and Interfaces, and the Use of Energetic Beams. Several of the technical activities of the program have been incorporated into the DOE Center of Excellence for the Synthesis and Processing of Advanced Materials.

This interdisciplinary program utilizes a broad array of sophisticated, state-of-the-art experimental and computational capabilities provided by other programs as well as this program. The major leveraged capabilities include: teraflop computers, various molecular beam epitaxy and chemical vapor deposition facilities, a broad range of materials synthesis and processing facilities, clean rooms for microfabrication and nanostructuring of materials, ion-beam accelerators, laser-based diagnostics, advanced optical and surface spectroscopies, unique combined high-pressure/low-temperature facilities, and electron, scanning tunneling, atom tracking and atomic force microscopies.
