摘要：

The effects of N+ and Ne+ ions impinging on a graphite target are studied by ultraviolet photoelectron spectroscopy. Changes in the valence band of the N+-irradiated graphite surface are found to be inherently different from the Ne+-ion-induced structural modification. They reveal a build-up of additional pi-defect states at the top of the band, and confirm what appears to be a distinct character of the influence of nitrogen on an amorphous carbon matrix.
