Abstract

We investigate the impact of tip changes on atomic-scale non-contact atomic force microscopy (NC-AFM) contrast formation when imaging a CaF₂(111) surface. A change of the atomic contrast is explained by a polarity change of the tip-terminating cluster or by a polarity-preserving tip change via the re-arrangement of the foremost atoms. Based on the established understanding of the unique contrast patterns on CaF₂(111), polarity-preserving and polarity-changing tip changes can be identified unambiguously. From analyzing a large set of images, we find that the vast majority of tip changes tend to result in negative tip termination. This analysis delivers hints for tip configurations suitable for stable imaging of CaF₂(111) surfaces.

萤石表面非接触原子力显微镜成像中尖端极性变化的趋势。

当对CaF2（111）表面成像时，我们研究了尖端变化对原子尺度非接触原子力显微镜（NC-AFM）对比度形成的影响。原子对比的变化可以通过尖端终止簇的极性变化或通过最前面原子的重排而保持极性的尖端变化来解释。基于对CaF2（111）独特的对比模式的理解，可以明确地识别出保极性和变极性尖端的变化。通过对大量图像的分析，我们发现绝大多数尖端变化倾向于导致负尖端终止。该分析提供了适合于CaF2（111）表面稳定成像的尖端结构的提示。
