中文摘要:

      在KYKY-1000B型扫描电子显微镜(SEM)上所开发的与其联用的袖珍型扫描隧道显微镜(STM)主要有四个部分:(1)减震阻尼装置,(2)隧道探针,(3)探针扫描与逼近装置,(4)电子控制与图象采集系统。它的分辨率约为1nm.并用它观察了半导体光栅与硅上金膜的细微结构。

英文摘要:

      A pocket scanning tunnelling microscope(STM) has beenbuilt on a KYKY-1000B scanning electron microscope(SEM). It consists of (1) a vibration-reduced system. (2) tunnelling tip. (3) tip scanning and approch system. (4) electric control and image acquisition system. The resolution of STM is about 1 nm. The semiconductor grating and gold film have been measured with this SEM+STM combined system.
