✦ Synopsis

The electrical resistivity along 500 A thick carbon films has been measured from l-2 to 1100°K. The electrical resistivity measurements at high temperature indicate a change in the structure of the film beginning at about 670°K. In the theory of noncrystalline solids by Mott, the temperature dependence of the electrical conductivity o, at low temperature, is given by In o = A -BT-1'4 where A and B are constants. Whereas previous investigators have shown general agreement with Mott's relation, the present result at low temperature shows deviation from the In cr (Y T-II4 relation.
