本文报道了27keV Ar~+离子分别轰击Cu元素靶和CuAu合金靶时溅射Cu原子的同位素(~(63)Cu和~(65)Cu)分馏测量结果,发现:(1)对Cu元素靶,同位素分馏δ_f(~(63)Cu,~(65)Cu)=(62±27)‰,而对Cu-Au合金靶,δ_f=(5.9±1.6)‰;(2)δ_f(~(63)Cu,~(65)Cu)随发射角θ的变化对两者靶而言趋势是相似的,但在CuAu合金靶情况下,当θ≤40°时,δ_f((63)Cu,~(65)Cu)为负值。 相似文献

nm光谱线强度比值和光子产额随入射离子能量的变化趋势。在本实验能量范围内,辐射光谱线强度比值随入射离子能量增加几乎不变,而发射谱线的光子产额随入射离子能量的增加呈现出不同趋势:入射离子能量为450
keV时,光子产额出现极大值,入射离子能量超过450
keV时,光子产额随能量的增加而减少,其变化趋势与核阻止本领随能量增加的变化没有出现类同的变化特征。结合核阻止和电子阻止效应对实验结果进行了讨论,结果表明:入射离子能量低于450
keV时,核阻止在碰撞中起主导作用,入射离子能量高于450 keV时,电子阻止在碰撞中起主导作用。 相似文献

The principle of magnetron sputtering is introduced andthe balanced and unbalanced magnetrons are compared andthe necessity of unbalanced magnetrons is explained as well. Several recent developments in plasma magnetron sputtering, i.e., unbalanced magnetron sputtering, pulsed magnetron sputtering and ion assisted sputtering, are discussed. The recent developments of unbalanced magnetron systems and their incorporation with ion sources result in an understanding in growingimportance of the magnetron sputtering technology, which makes the technology an applicable deposition process for a variety of important films, such as wear-resistant films and decorative films. 相似文献

Total sputtering yields have been measured for SiO2 and Cu targets bombarded with Si ions at an incident energy between 500 keV and 5.0 MeV using a quartz crystal microbalance technique. In order to measure total yields accurately, we have developed a beam modulation technique to avoid the effect of thermal drift. In the MeV energy range, an ion penetrates through thin SiO2 and Cu targets and is implanted into a quartz crystal. Therefore, the thickness of these layers deposited on quartz crystals was carefully controlled to avoid damage of quartz crystal by incident ions. As a result, total sputtering yields of SiO2 increased with incident Si ion energy, while those of the Cu target decreased. The total yields of the SiO2 target were represented well by a power low of the electronic stopping power. 相似文献

The zirconia containing
12wt%Y2O3 thin films deposited by r.f. magnetron sputtering at 25℃
or 400℃, and then bombarded with Ar+ beam at room temperature were
characterized with XRD before and after Ar+ bombardment. It is found that a
series of phases formation and transformation happened, among them the mostimportant event
is that T' phase appeared after Ar+ irradiation andthe content of the T' phase
increased with the increase of Ar+ iondoses from 5×1015 to 6×1016

高剂量注入中离子溅射的影响 总被引:1,自引:0,他引:1
在离子注入材料改性的研究过程中(金属、绝缘材料和光学材料等),在许多场合下,要求注入的元素(如Fe中注入N、Y、Ph和Sn等)在靶子中占百分之几的含量,这就要求注入剂量高达10~(17)/cm~2到10~(12)/cm~2。由于离子注入的溅射效应在低能和大剂量注入中是相当明显的,因此,对这些元素高剂量注入后的杂质分布、溅射系数、溅射厚度和靶子中杂质的收集量做一分析是十分重要的。 相似文献
