补充资料:隧道电流型原子力显微镜
分子式:
CAS号:

性质:一种利用隧道电流作为检测方式的原子力显微镜。其工作原理是将一个对微弱力极为敏感的微悬臂(cantilever)的一端固定,而另一端接上一微小针尖;在扫描时,针尖尖端的原子与样品表面原子间存在的极微弱的吸引力或排斥力被控制为恒定。带有针尖的微悬臂就会对应于针尖与样品表面原子间作用力的等位面,在垂直于样品表面的方向上起伏运动,利用隧道电流记录微悬臂对应于扫描各点的位置变化,从而获得样品表面形貌的信息。这种显微镜适用于各种体系的表面分析及各种环境下的现场测定,导电样品和非导电样品均可测定,且应用范围可达104数量级,分辨率达原子级,在化学过程的在线分析、生物吸附质和化学吸附质的研究、表面机械能及表面力的测量、电绝缘体无机物(如盐、矿物质)的表面谱的表征等领域有广泛应用。
