Abstract
We have carried out scanning tunneling microscopy (STM) observations of unr econstructed regions on quenched Si(1 1 1) surfaces at 380 degrees C at a s canning speed of 1.7 s per frame. In the regions, it is found that single f aulted-halves of the dimer-adatom-stacking-fault (DAS) structure are formed isolatedly or at the edges of the surrounding DAS domains sharing one corn er hole. In such "living" regions, we have succeeded to observe sudden stru ctural changes of the faulted-halves during line scans in single frames of STM images. (C) 2000 Elsevier Science B.V.
