Abstract
We report on dynamical flipping of buckled dimers on the Si(001) surface at 5 K. A ordering of the buckled dimers has been observed to fluctuate at 5 K by using low-temperature scanning tunneling microscopy (STM). The flip-flop motion of the buckled dimers on the Si(001) surface exhibits symmetrical appearance in the STM images, independent of sample bias voltages and tunneling current.
