Effect of diamond like carbon (DLC) films coated by pulsed laser deposition technique on the electron emission characteristics of Mo-tips was examined. Turn-on voltage (Vo) was lowered from 80 volts for Mo-tips to 40 volts for DLC coated-tips and saturated anode current (I_<AS>) was increased from 〜44 μA for Mo-tips to 〜2.0 mA or DLC coated-tips. Emission conductance (Ge)has, therefore, been increased from 0.55 μmho with amplified factor of 〜100 due to the DLC coatings on the Mo-tips. Saturated anode current (I_<AS>) dropped rapidly operation. Raman spectrascopy and diffraction in transmission electron microscopy (TEM) revealed that the degradation of electron emission behavior can be ascribed to the conversion of SP^3 -bonds, the diamonds, to the SP^2-bonds, graphite. The transformation of the structure, on the other hand, is induced by the local heating of the DLC coatings.
