    Abstract: We present the soft x-ray spectroscopic study of the ultra-nanocrystal line diamond (UNCD) films with different surface treatments. The samples were prepared by means of microwave plasma enhanced chemical vapor deposition (MPECVD) and the different surface treatments are applied to alter their field emission properties. The electronic properties were subsequently examined by the soft x-ray absorption and x-ray emission spectroscopy at carbon 1s threshold. From the experimental results, there is no significant variation in electronic structure of oxygen- and hydrogen-plasma treated UNCD films. On the other hand, the biased treated UNCD film shows more remarkable change on the sp(2) and sp(3) states. The formation of sp(2) bonding and the reduction of sp(3) bonding are the consequence of the improved electron field emission properties.
