Investigate the low-temperature atomic-scale structural configurations and dynamic phase transitions on the Si(100) surface at 6 K.
Cooled the Si(100) surface to 6 K to freeze thermal fluctuations previously seen at 120–140 K.
Imaged the surface with atomic resolution using scanning tunneling microscopy to track dimer row configurations and phase defects.
Observed reversible, atomically resolved phase transitions between c(4×2) and p(2×2) arrangements on the Si(100) surface at 6 K.
Identified that transitions are driven by the movement of phase defects along dimer rows via dimer flip-flop motion.
Visualized the continuous creation and annihilation of anti-phase domains at phase boundaries.
