摘要
At 80 K, not all the: aimers of Si(100) appear buckled in the scanning tunneling microscopy (STM) images but a certain number of the dimers are observed in a symmetric configuration. We report on observations of a two-dimensional spontaneous fluctuation of the symmetric double left right arrow buckled dimer domains at some particular locations. We interpret the spontaneous fluctuation to be induced by the competition of several antiphased c(4 x 2) buckled domains to expand. The fluctuation of domains was interpreted by two mechanisms: a fast switching between buckled dimer domains and symmetric dimers induced by migration of P defects.
