Objectives
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.

Course instructors
Pierangelo Gröning
got his master in Electrical Engineering in 1981 from the Engineer School Biel/Bienne (CH). In October 1981, he joined Brown Boveri Company (later ABB) where he developed high power electronic converters for rail ways. After five years in industry he went back to academia and studied Physics and Mathematics at the University of Fribourg (CH), where he obtained his PhD in Solid State Physics in 1993. From 1993 to 2002 he was Staff Scientist and Lecturer at the University of Fribourg (CH). In 2002, he joined the Swiss Federal Laboratories of Materials Testing and Research (Empa), where he set-up a new research section active in Solid State Physics and on organic and inorganic nanostructures on surfaces.
Since April 2006 Dr. Gröning is head of the Department “Advanced Materials and Surfaces” and member of the board of directors at Empa. He is author/co-author of more than 110 scientific publications and was awarded with the Swiss Technology Award in 1997. His scientific interests are on the electronic properties of carbon nanotubes, the synthesis of organic nanowires and their electronic properties, molecular-self assembly at surfaces, and on the surface and electronic structure of quasicrystals and complex metallic alloys.

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).
