    Initial Stage of Oxidation on Si(111)-7×7 Surface Investigated by Scanning Tunneling Microscope

    The initial oxidation of Si(111)-7×7 surface has been investigated by taking the STM images of samples dosed with oxygen at room temperature and high temperatures between 500 °C and 750 °C. In particular, diff...
