摘要: 扫描隧道显微镜又叫STM。STM具有惊人的分辨本领，水平分辨率小于0.1纳米，垂直分辨率小于0.001纳米。一般来讲，物体在固态下原子之间的距离在零点一到零点几个纳米之间。在扫描隧道显微镜下，导电物质表面结构的原子、分子状态清晰可见。STM的基本工作原理是利用探针与样品在近距离（小于0.1纳米）时，由于二者存在电位差而产生隧道电流，隧道电流对距离非常敏感；当控制压电陶瓷使探针在样品表面扫描时，由于样品表面高低不平而使针尖与样品之间的距离发生变化，而距离的变化引起了隧道电流的变化；控制和记录隧道电流的变化，并把信号送入计算机进行处理，就可以得到样品表面高分辨率的形貌图像。

The scanning tunnel microscope calls STM. STM has the astonishingresolving ability, the horizontal resolution is smaller than 0.1nanometer, the vertical resolution is smaller than 0.001 nanometer.Generally says, the object between the atomic distance in 0.1 arriveszero under the solid state to select between several nanometer. Underthe scanning tunnel microscope, the conducting material surfacetexture atom, the molecular state is clearly discernible. The STMbasic principle of work is using the probe and the sample (are smallerthan 0.1 nanometer) when the near distance, as a result of the twoexistence potential difference produces the tunnel electric current,the tunnel electric current to is away from extremely sensitively;When the control piezoelectricity ceramics cause the probe when thesample surface scanning, because the sample surface unevens causesbetween the needle-tip and the sample distance changes, but thedistance change has caused the tunnel electric current change; Thecon
