对动态扫描力显微镜中金属纳米团簇等高模成像的实验和理论进行了定量比较。我们用Pd/MgO(001)体系解释了反差形成的基本机制。对比表明，由于尖端最后一个纳米的锐度，纳米团簇的形状和大小得到了精确的成像。这一定量比较证明了我们先前提出的对比度形成模型。
A quantitative comparison between experiment and theory is given for the constant height mode imaging of metal nanoclusters in dynamic scanning force microscopy. We explain the fundamental mechanisms in the contrast formation with the help of the system Pd/MgO(001). The comparison shows that the shape and size of nanoclusters are precisely imaged due to the sharpness of the tip’s last nanometer. This quantitative comparison proves our previously proposed model for the contrast formation.
