摘要：

The transformation of the (2 × 1) structure of cleaved Si(111) to the (7 × 7) structure with thermal annealing has been investigated with reflection high-energy electron diffraction (RHEED). An intermediate (5 × 5) phase is observed, making the reaction sequence (2 × 1) → (5 × 5) → (7 × 7). Initial results of the transformation kinetics show that the decay of the total area of the (2 × 1) phase follows a power law with an exponent x ≈ -1 2. © 1990.
