动态摩擦力显微镜（DFFM）是一种基于原子力显微镜（AFM）的技术，其中悬臂的共振振荡由样品的横向致动激发。在此过程中，与样品接触的原子力显微镜针尖经历复杂的运动，其中包括粘附和滑动的交替周期。因此，DFFM可以访问摩擦中的动态过渡效果，这是其他技术无法访问的。以石墨表面的锑纳米颗粒为模型系统，分析了摩擦力和表面形貌的综合影响如何影响DFFM的不同实验配置。基于实验结果，例如，分数共振和带激发成像策略之间的对比度反演，以提取可靠的摩擦学信息从DFFM图像设计。出版社：AIP Publishing
Dynamic Friction Force Microscopy (DFFM) is a technique based on Atomic Force Microscopy (AFM) where resonance oscillations of the cantilever are excited by lateral actuation of the sample. During this process, the AFM tip in contact with the sample undergoes a complex movement which consists of alternating periods of sticking and sliding. Therefore, DFFM can give access to dynamic transition effects in friction that are not accessible by alternative techniques. Using antimony nanoparticles on graphite as a model system, we analyzed how combined influences of friction and topography can effect different experimental configurations of DFFM. Based on the experimental results, for example, contrast inversion between fractional resonance and band excitation imaging strategies to extract reliable tribological information from DFFM images are devised.
