222 Appendix C. European Roundtable Discussions A group of scientists from or near Stuttgart were invited to a roundtable discussion of their various research projects on nanoscale technology and materials. Names of attendees and their affiliations are listed above. The highlights of these presentations are given below, by institution. Max-Planck-Institut für Festkörperforschung (MPI FKF) Tel: (49) 711-689 0; Fax: (49) 711-689 1010 http://www.mpi-stuttgart.mpg.de/start.html Professor Dr. Klaus v. Klitzing Professor v. Klitzing described research on functional nanodevices at the Max Planck Institute (MPI). He also discussed the broader view of work on nanotechnology in Germany, particularly on III-V quantum structure devices. Summaries of work on this subject, financial supporters, and details of technical progress are summarized in III-V-Elektronik Mesoskopische Bauelemente (in German). There is broad cooperation between universities and industry on this project. Professor v. Klitzing briefly described some of his own research, including MBE growth and etching system for study of GaAs/AlAs/ AlGaAs:15/AlAs:6/GaAs and quantum dot lasers GaInP and InP. The ultimate single-electron tunneling transistor—which is being addressed at many laboratories—is the goal of much of the research. The electronic properties of clusters are studied, e.g., gold clusters with well-defined number of atoms as contacts and islands for charge transfer. Some examples of low-dimensional electronic systems prepared by the chemistry department of the MPI FKF Stuttgart are “0-dimensional” CS 11 O 3 , “one-dimensional” Na 5 Ba 3 N, and “two-dimensional” Ba 2 N crystals. Prof. v. Klitzing is skeptical about the ultimate use of nano-semiconductor systems, such as quantum dots, for applications in mainstream microelectronics. Dr. I.M.L. Billas Dr. Billas in the group of Prof. Dr. T.P. Martin described the group’s work on clusters studied by means of time-of-flight mass spectrometry. Much of the work deals with metal-covered C 60 or C 70 molecules. C 60 is an ideal template for growing shells of metal atoms. Several systems include alkali-metal, alkaline-earth-metal, and transition-metal-covered fullerenes. Fabrication of new exotic magnetic nanostructures is part of an interregional research project “magnetic nanostructures,” which includes researchers from adjacent regions of France and Germany partially funded by regional governments. The project collaborators are listed below:
Appendix C. European Roundtable Discussions 223 France: Rhône-Alpes region: Dr. A. Perez, University C. Bernard, Lyon Prof. Dr. M. Broyer, University C. Bernard, Lyon http://www.univ-lyon.fr/ Prof. Dr. B. Barbara, CNRS, Grenoble Dr. K. Hasselbach, CNRS, Grenoble http://labs.polycnrs-gre.fr/ Alsace region: Prof. Dr. J.-P. Bucher, University L. Pasteur, Strasbourg http://www-ulp.u-strasbg.fr/ Germany: Baden-Würtemberg region: Prof. Dr. H. Haberland, Frieburg University Prof. Dr. T.P. Martin, MPI, Stuttgart Prof. Dr. D. Weiss, Stuttgart and Regensburg The research of this program includes fabrication and stabilization of nanosize magnetic structures (magnetic dots and clusters) and their characterization by time-of-flight mass spectroscopy, TEM and HRTEM, XRD, and absorption techniques, Rutherford Backscattering, and XPS. Magnetic properties are measured by magnetic force microscopy, magnetometry (microSQUIDs), magnetotransport measurements, and ultrafast magnetooptical measurements. Max-Planck-Institut für Metallforschung http://wwwmf.mpi-stuttgart.mpg.de/ Dr. Thomas Wagner Dr. Wagner is staff scientist at the Max-Planck Institut für Metallforschung leading the “Thin Film Synthesis and Processing” group. His current research uses STM, TEM, coupled with standard surface analysis techniques, to characterize metal and ceramic films, multilayers, and alloy films with defined chemical composition grown by MBE and sputter deposition on a variety of substrates. The main thrust of his group is to investigate physico-chemical mechanisms of thin film growth like solid state reactions, nucleation processes, and interface formation during film deposition. The following thin film systems are under investigation: Metal/Ceramic Nb, Cu/Al 2 O 3 Al, Ag/MgAl 2 O 4 Si, Pd, Cu/SrTiO 3 Ceramic/Ceramic Ti 2 O 3 /Al 2 O 3 ZrO 2 /Al 2 O 3 TiO 2 /Al 2 O 3 In addition, special thin film systems are grown to study their mechanical properties (e.g., alloy films), thermal stability (grain growth, stability of boundaries), atomistic structure, and bonding interfaces.
