| Abstract: | We review transport measurements on single-walled carbon nanotubes contacted by metal electrodes. At room temperature some
devices show transistor action similar to that of p-channel field effect transistors, while others behave as gate-voltage
independent wires. At low temperatures transport is usually dominated by Coulomb blockade. In this regime the quantum eigenstates
of the finite-length tubes can be studied. At higher temperatures power law behaviour is observed for the temperature and
bias dependence of the conductance. This is consistent with tunneling into a one-dimensional Luttinger liquid in a nanotube.
We also discuss recent developments in contacting nanotubes which should soon allow study of their intrinsic transport properties.
