Paper Abstract

The effects of laser-induced structural modifications of the diamond surface are considered in relation to i) laser activation of diamond for direct electroless metallization ii) enhanced electron field emission from laser-ablated diamond films. It is shown that both the catalytic activity for electroless metal plating and reduced emission fields of the laser-ablated diamond surface correlate with the modifications in the valence-band structure, a specific feature of which is the appearance of the occupied electronic states in the gap. The laser ablation technique is applied for fabricating periodical microstructures at the diamond film surface, and results of the field emission testing of the produced 1D microstructures are presented.
