This session is organised in collaboration with EMPA.
Carbon nanotubes are tiny, hollow tubes made of pure carbon just a few nanometers in diameter and up to few hundreds microns in length. They exhibit unique electrical properties, efficient heat conductivity and excellent mechanical strength. Due to their outstanding physical properties carbon nanotubes are one of nanotech’s most promising molecular building blocks. Carbon nanotubes are already used in composites to make them stronger and lighter, e.g. for tennis rackets or bicycle frames. Carbon nanotube based cold electron sources for flat panel displays, X-ray sources or microwave amplifiers are close to be ready for the market.
The first part of lecture is an introduction on the physical properties of carbon nanotubes as well as their synthesis and production techniques. The second part is focused on applications. On the basis of numerous examples the great technological potential of carbon nanotubes is pointed out.
The course addresses a scientific and technological audience coming from industry as well as from academia.
Dr Pierangelo Gröning is head of the “Advanced Materials and Surfaces” Department at Swiss Federal Laboratories of Materials Testing and Research (EMPA)in Thun and member of the board of directors. P. Gröning received his diploma in electro technique from the engineer school in Biel, Switzerland in 1981. After a period of four years, where he worked on the development of electronic high power converters at BCC later ABB in Turgi, Switzerland, he studied physics and mathematics at the University of Fribourg, Switzerland. He received his diploma and Ph.D. degree in 1989 and 1993, respectively. From 1993 till 2002 he was responsible for the research activities on plasma treatment and deposition in the physics department at the University of Fribourg. In 2002 he joined EMPA in Thun, Switzerland.
Dr Pascal Ruffieux is research staff member at the Swiss Federal Laboratory for Materials Testing & Research (EMPA) since 2008. His research interests are focused on following fields: - Nanoscale science with self-organized molecular and atomic structures at surfaces (supramolecular engineering at surfaces; Molecular self-assembly on solid surfaces; Surface physics and chemistry of atomic and molecular adsorbates). - Scattering dynamics on sp2-bonded carbon structures (electronic and structural aspects of hydrogen adsorption on sp2 carbon; scattering dynamics of defects on single-walled carbon nanotubes; defect-related creation of confined states on single-walled carbon nanotubes). - Properties of nanostructure surfaces (local properties of nanostructured template surfaces; determination of surface potential landscape; thin films and surface alloys; relation between geometrical and electronic properties).
