SPM-8100FM

High-Resolution Scanning Probe Microscope

 

观察生动的纳米世界

使用调频模式的全新型HR-SP൩M高分辨率原子力显微镜,不仅可以在空气及液体环境中实现更高分辨率,而且初次观察到了固液界面的水化/溶剂化作用的液体分层。

HR-SPM: 高分辨原子力显微镜

HR-SPM特点


使用调频模式
空气和液体中的噪音降低到传统模式的二十分之一
在空气和液体环境中也能达到更高真空原子力显微镜的分辨率

现有的扫描探针显微镜 (scanning p♎robe microscopes)和原子力显微镜(atဣomic force microscopes) 通常使用调幅模式(amplitude modulation).从原理上, 调频模式(frequency modulation) 可以达到更高的分辨率。

与现有SPM/AFM的区别


液体环境中原子分辨率观察

NaCl饱和溶液中观察固体表面的原子排列。使用调幅模式的传统原子力显微镜,图像完全被噪音遮盖(左图),但在调频模式下,原子排列清晰可见(右图)。调频模式实现了实实在在的原子级分辨率。

KPFM: 扫描开尔文显微镜

TiO2基底上的Pt颗粒, 通过KPFM进行表面电势的测定,TiO2基版上的Pt催化粒子可被清晰识别。同时可以观察到数纳米大小的Pt粒子和基板间的电荷交换。右图中,红色区域是正电势,蓝色区域是负电势。对于PKFM观🌞察,FM模式也大幅提高了分辨率。 

 

 

注: KPFM需要特定的基底。
