Abstract
Single wall carbon nanotubes have attracted considerable interest as
they represent the one-dimensional form of carbon. In addition to the fundamental
interests related to this material, there are high expectations for its
applications such as building blocks for future electronics, tips for scanning
microscopy, carrier for biologically active substances and many more. Here,
I will give an introductory lecture to the physics of SWCNTs focused on
spectroscopic studies such as optical absorption, fluorescense, scanning
tunneling spectroscopy, and magnetic resonance. Special emphasis will be
given on Raman spectroscopy aimed at the study of nanotubes when the interior
of the tube is filled. I report the first successful synthesis of a paramagnetic
spin encapsulated in SWCNT in the form of N@C60@SWCNT as evidenced by electron
spin resonance spectroscopy.
