摘要：

Structural and field-emission studies of diamond-coated tips were performed. RHEED and HRTEM investigations have shown that diamond coatings are polycrystalline with average sizes of crystallites between 10 and 100 nm. Field-emission measurements demonstrate strong emission from blunt tips with radii of 0.4 mu m. After annealing in oxygen the emission current decreased by two orders of magnitude. Two approaches for the explanation of the observed emission behavior were proposed: (1) NEA-affected emission and (2) emission from sharp nano-size points.
