Abstract
The N doping effect on the electrical conductivity and electron emission property for diamond like carbon (DLC) films deposited by PECVD has been studied. The electrical conductivity can be widely varied by n-type doping of the DLC. The relationship between the prefactor of conductivity and the conductivity activation energy satisfy the Meyer-Neldel relation: /spl sigma//sub 0/=/spl sigma//sub 00/exp(AE/sub a/) with A=19 eV/sup -1/ and /spl sigma//sub 00/=9/spl times/10/sup -8/ S/cm. The emission currents for heavily N doped DLC films are much higher than undoped DLC even though lightly N doped films show much smaller currents.
