我们提出了一个三维映射例行探测固-液界面使用调频原子力显微镜的实施。我们的实施能够同时快速灵活地采集多达20个通道的数据。所获取的数据可以直接与商业原子力显微镜控制器同步，使得我们的例程可以容易地扩展到需要额外数据通道的相关技术，例如，开尔文探针力显微镜。此外，尖端与样品的最接近受到用户定义的阈值的限制，从而提供了防止尖端潜在损坏的可能性。我们的设置的性能是通过可视化的水化结构以上的方解石（10.4）在水中的表面。
We present the implementation of a three-dimensional mapping routine for probing solid-liquid interfaces using frequency modulation atomic force microscopy. Our implementation enables fast and flexible data acquisition of up to 20 channels simultaneously. The acquired data can be directly synchronized with commercial atomic force microscope controllers, making our routine easily extendable for related techniques that require additional data channels, e.g., Kelvin probe force microscopy. Moreover, the closest approach of the tip to the sample is limited by a user-defined threshold, providing the possibility to prevent potential damage to the tip. The performance of our setup is demonstrated by visualizing the hydration structure above the calcite (10.4) surface in water.
