The National Academy of Sciences is a private, nonprofit, self-perpetuating society of distinguished scholars engaged in scientific and engineering research, dedicated to the furtherance of science and technology and to their use for the general welfare. Upon the authority of the charter granted to it by the Congress in 1863, the Academy has a mandate that requires it to advise the federal govern- ment on scientific and technical matters. Dr. Ralph J. Cicerone is president of the National Academy of Sciences. The National Academy of Engineering was established in 1964, under the charter of the National Academy of Sciences, as a parallel organization of outstanding engineers. It is autonomous in its administration and in the selection of its members, sharing with the National Academy of Sciences the responsibility for advising the federal government. The National Academy of Engineering also sponsors engineering programs aimed at meeting national needs, encourages education and research, and recognizes the superior achievements of engineers. Dr. Charles M. Vest is president of the National Academy of Engineering. The Institute of Medicine was established in 1970 by the National Academy of Sciences to secure the services of eminent members of appropriate professions in the examination of policy matters pertaining to the health of the public. The Institute acts under the responsibility given to the National Academy of Sciences by its congressional charter to be an adviser to the federal government and, upon its own initiative, to identify issues of medical care, research, and education. Dr. Harvey V. Fineberg is president of the Institute of Medicine. The National Research Council was organized by the National Academy of Sciences in 1916 to associate the broad community of science and technology with the Academyâs purposes of furthering knowledge and advising the federal government. Functioning in accordance with general policies determined by the Academy, the Council has become the principal operating agency of both the National Academy of Sciences and the National Academy of Engineering in providing services to the government, the public, and the scientific and engineering communities. The Council is administered jointly by both Academies and the Institute of Medicine. Dr. Ralph J. Cicerone and Dr. Charles M. Vest are chair and vice chair, respectively, of the National Research Council. www.national-academies.org

Preface The National Research Council of the National Academies convened the Com- mittee for an Assessment of and Outlook for New Materials Synthesis and Crystal Growth to assess current work and new opportunities in the United States in the field of the discovery and growth of crystalline materials. The Solid State Sciences Committee of the Board on Physics and Astronomy developed the charge for this study in consultation with the studyâs sponsors at the Department of Energy and the National Science Foundation. The committee was charged to define the research areas in this field, to determine the health of activities in the United States in those areas, to identify future opportunities, and then to suggest strategies to best meet those opportunities. The complete charge is reproduced in Appendix A. The committee that prepared this report is composed of experts from the many academic disciplines falling within this field and includes members from the different types of institutionsâacademic, government, and industrial research laboratoriesâinvolved with this research (see Appendix B for biographical sketches of the committee members). The full committee met in person three times (see Appendix C) to address its charge. The committee formed subgroups to study s Â pecific areas in further detail and to develop the text of the final report. At its meet- ings, the committee heard from experts in the field and from the federal agencies that support research in this field. Conference calls and e-mail correspondence were used to coordinate the work of the committee between meetings. This final report reflects not only the committeeâs concerns regarding the current level of activity in the United States in this field but also its enthusiasm and excitement for research opportunities presented now and in the foreseeable future in these areas. ix
Preface As committee chair, I am grateful to the committee members for their wisdom, cooperation, and commitment to ensuring the development of a comprehensive report. Paul S. Peercy, Chair Committee for an Assessment of and Outlook for New Materials Synthesis and Crystal Growth
