Abstract
We continuously observed the growth of the dimer-adatom-stacking-fault (DAS ) domain, in unreconstructed regions remaining after quenching a Si(111) su rface to 370-380 degrees C, by using scanning tunneling microscopy. It was observed that a single faulted (F) half of the 9 x 9 unit cell of the DAS s tructure grows to a small 9 x 9 DAS domain. Continuous measurements showed that new F-halves are created sharing corner holes with existing F-halves. The creation of new isolated F-halves was very seldom at 370-380 degrees C, and the region of the DAS structure was grown by expanding the area of the existing DAS domains.
