中文摘要	A patterned array of diamond-like carbon (DLC) was grown on anodic aluminumoxide (AAO) template by ﬁltered cathodic arc plasma (FCAP) technique at room temperature. The diameters of patterned array of DLC were 150 nm, and the patterned array density was estimated to ～109cm-2. A broad asymmetric band ranging from 1000 cm-1to 2000 cm-1 was detected by Raman spectrum attributed to characteristic band of DLC. The fraction of sp3 bonded carbon atoms of the patterned array of DLC was measured by X-ray photoelectron spectrum (XPS) and the ratio was about 62.4%. Field emission properties of the patterned array of DLC were investigated. A low turn-on ﬁeld of 3.4 V/mm at 10 mA/cm2 with an emission area of 3.14 mm2was achieved. The results indicated that the electrons were emitted under both the effect of enhanced ﬁeld because of the geometry and the work function of the DLC sample. Based on Fowler–Nordheim plot, the values of work function for the patterned array of DLC were estimated in range of 0.38 to 1.75 from a linearity plot.
