摘要:

自原子力显微镜AFM诞生以来,动态方法已经非常富有成效,通过建立方法来量化纳米尺度上的耗散力和保守力,并提供一种手段来向样品施加高分辨率的温和力。在这里,我们回顾的发展,涵盖了十多年的工作,能量耗散,相位对比和提取相关的材料性能从可观的。我们描述了试图恢复材料的性能,通过一维的振幅和相位曲线从力模型和探索这些方法的演变方面的力重建,适合的实验测量,和最近的进展,多频AFM。

英文摘要:

Since the inception of the atomic force microscope AFM, dynamic methods have been very fruitful by establishing methods to quantify dissipative and conservative forces in the nanoscale and by providing a means to apply gentle forces to the samples with high resolution. Here we review developments that cover over a decade of our work on energy dissipation, phase contrast and the extraction of relevant material properties from observables. We describe the attempts to recover material properties via one dimensional amplitude and phase curves from force models and explore the evolution of these methods in terms of force reconstruction, fits of experimental measurements, and the more recent advances in multifrequency AFM.
