  • 专业解析

    扫描隧道显微镜(Scanning Tunneling Microscope,简称STM)是一种基于量子隧穿效应原理的纳米级表面分析仪器。它通过探针尖端与样品表面之间的微小电流变化,实现原子级分辨率的表面形貌成像。当探针与样品间距缩小到纳米级别时,在施加偏置电压的条件下,电子会穿过势垒形成隧穿电流。该电流对间距极为敏感,通过反馈系统控制探针高度,可精确记录表面起伏信息。

    STM的核心特性包括:

    1. 原子级分辨率:可观测到单个原子排列,横向分辨率达0.1纳米,纵向分辨率达0.01纳米;
    2. 非破坏性检测:工作于超高真空环境时,可在不损伤样品的前提下进行表征;
    3. 多功能应用:不仅能成像表面形貌,还可操纵原子、测量电子态密度分布。

    该技术由盖尔德·宾宁(Gerd Binnig)和海因里希·罗雷尔(Heinrich Rohrer)于1981年在IBM苏黎世实验室发明,并于1986年获得诺贝尔物理学奖。现代STM广泛应用于材料科学、半导体工业、催化研究和生物分子结构分析领域,例如石墨烯表面缺陷检测和DNA分子构象研究。其衍生技术如原子力显微镜(AFM)进一步扩展了纳米表征技术的应用范围。
