Appendix C. European Roundtable Discussions 237
Individual Presentations from Research Groups
The last part of the workshop at KTH was devoted to presentations from
individuals who gave brief overviews of the nanoscale science and
technology research efforts in their individual groups.
Prof. David Haviland, now at KTH, described his efforts in nanostructure
physics. He uses lithographically defined nanostructures to study electronic
transport phenomena such as Coulomb blockage, spin-dependent transport,
and theory involving quantum optics in nanostructures and diffraction optics
in nanostructures. Prof. Haviland collaborates closely with Profs. P. Delsing
and T. Cleason of the Single Electron Group at Chalmers.
Prof. K.V. Rao of KTH described his group’s research in large scale
applications of soft magnetic materials. The work is entitled Functional
Nanometric Science and consists of three primary thrusts:
1. Production by several different techniques such as thin film deposition
using rf laser ablation, rf sputtering, and e-beam deposition; rapid
solidification technology such as melt spinning to produce GMR
materials; and chemical co-precipitation techniques.
2. Characterization using surface probe microscopy; atomic force, scanning
tunneling, and magnetic force microscopy (AFM, STM, and MFM) are
key techniques.
3. Applications of nanostructures, under study as magnetic dots, novel
GMR materials, high T c -based tapes from nanosize precursors,
nanolithography and carbon nanotubes and fullerenes as nanoscale
electrodes.
Prof. Arne Rosén of Chalmers University of Technology and Göteborg
University presented a detailed overview of the nanoscale science being
carried out in his Molecular Physics Group. The title of his talk, “Clusters,
Fullerenes, Nanotubes and Nanowires: New Building Blocks in
Nanoscience,” accurately describes the presentation. A brief description of
the key areas of interest is given here. The key research areas in his group
cover six main themes:
1. surfaces and catalysis
2. metal clusters
3. fullerenes and nanotubes
4. combustion engine research (there is a center dedicated to this work)
5. medical-related research
6. related other projects
Two areas that are almost entirely devoted to nanoscale work are the
metal cluster and the fullerene and nanotube research areas. In both areas
there is a strong experimental effort, coupled with a strong theoretical effort.
