通过 AFM针尖诱导氧化加工 Ti膜的实验得到了凸出的 Ti膜氧化物高度与偏置电压成线性关系 ,并和针尖扫描速度成负对数关系 ,在前人的基础上深化了 AFM针尖诱导氧化加工的机理和理论模型 ,分析得到了合适的加工条件即 :偏压为 8V,扫描速度为 0 .1μm/ s.
The mechanism of AFM tip induced oxidation is analyzed in details.According to the experimental results of AFM tip induced oxidation of titanium under various voltage biases and scanning speeds,it is found that the height of the titanium oxidation is linear with the voltage bias and with the negative log of the scanning speed.Based on the current theories,the mechanism and the theoretical model of AFM tip induced oxidation are improved,and the proper conditions,voltage bias of 8V and scanning speed of 0.1μm/s,to perform AFM oxidation of titanium are got.
