Abstract
Electrical properties of a single piece of carbon micro coil with the diame ter of several mu m and the length of several mm are studied. The conductiv ity of the single coil is 30 similar to 100 S/cm. The resistance increases step wise by stretching due to disconnection between helices. The temperatu re dependence of conductivity, which shows a semi-conductive behavior with the apparent activation energy of about 4 meV, indicates the variable range hopping as the transport mechanism.
