International C.N.R.S. Colloquium on Metal— Nonmetal 7)’ansitions, Austrans, France. An International Committee with the aim of giving a coherent presentation of some of the important ideas and results in this field has selected eight topics to be covered. Each topic will be presented in a general way in a plenary session by one or two speakers. Particular aspects will then be developed in several shorter talks, interspersed with discussion periods. To accommodate the remaining communications, special informal poster sessions wifi be arranged every evening after dinner. The total number of participants will be limited to one hundred. All the communications will be published in the “Journal de Physique” as a special volume in the series “Colloques Internationaux du C.N.R.S.”, in either of the working languages, English and French. The topics selected, together with the names of plenary session speakers are the following: 1. Metal—nonmetal transitions in transition metal compounds: experiment (J.M.D. Coey, J.M. Honig). 2. Structural defects and non-stoichiometry in transition metal compounds (S. Amelinckx). 3. Layered compounds: charge density waves in transition metal compounds (D. Jerome, P.M. Williams). 4. Theories of correlation and collective distortion in narrow bands (M. Weger). 5. Metal—nonmetal transitions in rare earth cornpounds: experiment and theory (D. Wohileben). 6. Impurity band conduction: experiment and theory (N.F. Mott). 7. Interrelation of correlation and disorder: experiment and theory (D. Thouless, P.W. Anderson). 8. New perspectives for the metal—nonmetal transition (round table discussion) (N.F. Mott,P.W. Ajiderson, W. Kohn, J. Friedel). Information: The Secretary, Colloquium on Metal—Nonmetal Transitions, C.N.R.S. Groupe des Transitions de Phases, B .P. 166X 38062 Grenoble, France.
Second InternationalMeeting on Cadmium Telluride and its Applications, Strasbourg, France. The conference will deal with the preparation, clystal growth, and defect properties of the compound. It will also consider applications to various devices such as electrooptic modulators, laser windows, ‘y.ray detectors, solar cells, and electroluminescent light sources, as well as aspects of applying such devicesto various practical problems. There will be a number of invited reviews on perti. nent topics and original contributions of 15 mm duration can still be accepted. Attendance is restricted to persons active in these fields and invitations may be obtained from: P. Siffert, Centre des Recherches Nucleaires, 67037 Strasbourg, France. R.O. Bell, Mobil Tyco Solar Energy Corp. 16 Hickory Drive, Waltham, Mass. 02154, U.S.A.

17—29 August 1976 Chemistry and Physics ofOne-dimensionaiMetals A NATO Advanced Study Institute on this topic will be held at Bozen/Italy. Lecture courses will cover the basic theory, the synthesis and physical investigation of organic anda inorganic conductors. This includes discussionone-dimensional on the electronic properties of these compounds and of the physical methods which have been used to identify one-dimensional solid state behaviour. Further details and application forms are available from: Prof. Dr. Heimo J. Keller, Anorganisch-Chemisches Institut der Universität Heidelberg, D 6900 Heidelberg I, Im Neuenheimer Feld 270/GFR. 30 August—3 September 1976 XII International Conference on the Physics of Semiconductors, Roma, Italy.

CALENDAR OF SOLID STATE EVENTS
The Rome Semiconductor Conference, 13th of the series of international conferences sponsored by IUPAP (International Union of Pure and Applied Physics), wifi mainly deal with the fundamental aspects of semiconductor physics, following a pattern that has characterized all previous meetings. Topics that have drawn focal attention in the most recent meetings of Boston (1970), Warsaw (1972) and Stuttgart (1974), will again be emphasized, along with new rapidly developing subjects. The Organizing Committee is tentatively proposing the following list of topics to be given particular emphasis: Optical properties; Transport phenomena; Surface and Interface Properties; Junction and heterojunctions; High-intensity spectroscopy;Photoemission and Recombination processes; One and two-dimensional effects; Metal-semiconductor transitions; Narrow-gap semiconductors; Amorphous semiconductors; New materials and devices; Many-body effects; Lattice dynamics. Invited speakers will be selected to cover the most interesting developments. Contributed papers reporting significant results will also be considered, unless they have been presented elsewhere. All papers will be published in the Conference Proceedings. The Conference sessions wifi be held at the Auditorium della Technica, located at EUR, a modern business district on the southern edge of Rome. Detailed topological information will be provided in due time. A number of hotels are available in the area. However, as transportation to and from downtown Rome is very convenient, participants wishing to lodge in the city will meet no difficulties in commuting. The Organizing Committee will accept applications up to a maximum of 1000 participants. All suggestions and requests for information of a technical nature should be forwarded to: Prof. Andrea Frova, Instituto di Fisica G. Marconi, P. le dde Scienze 5, 00185, Roma, Italy. 30 August—4 September 1976 International Conference on Organic Conductors and Semiconductors, Siofok, Hungary. This conference is sponsored by the Hungarian Academy of Sciences and the Central Research Institute for Physics. The conference will be concerned with the current status and directions of theoretical and experimental research on organic conductors and semiconductors. The topics ~ ill include t”e physical properties of charge transfer salts and mixea valence compounds and the chemical aspects of these materials; metal—insulator

transitions in quasi one-dimensional systems, and model descriptions of low-dimensional cooperative phenomena. Emphasis will be laid on the physical properties and on the effect connected with the low dimensional character of these systems. Information: G. Gruner or J. Sólyom, Central Research Institute for Physics, H-i 525 Budapest, P.O.B. 49, Hungary. 30 August—il September, 1976 Electrons in Finite and Infinite Structures, Gent, Belgium. A NATO Advanced Study Institute on “Electrons in Finite and Infinite Structures” wifi be held at the State University of Gent, Belgium. Information and application forms available from: Prof. Dr. P. Phariseau, Rijksuniversiteit Gent, Krijgslaan 271, gebouw S9, B-9000 Gent, Belgium. 1—3 September 1976 International Conference on Magneto-Optics, Zurich, Switzerland. The conference is planned to be held at the Physics Department of the Swiss Federal Institute of Technology (ETH) in Zurich-Honggerberg, as a satellite meeting to the International Magnetism Conference in Amsterdam (September 6—10, 1976). The conference is recommended by the EPS Magnetism Section of the Condensed Matter Division and IUPAP. It is the aim of the conference to bring together scientists working in the field of Magneto-Optics and to discuss various aspects like methods of measurement, experimental and theoretical research and applications. Information: Prof. Dr. P. Wachter, Laboratorium fur Festkorperphysik ETHZ, Honggerberg, CH 8049 Zurich, Switzerland. 1—4 September 1976 Crystal Field Effects in Metals and Alloys, Zurich, Switzerland. The International Conference on Crystal Field Effects in Metals and Alloys will be held at the Swiss
Pergamon Press.
