| Abstract: | A recently developed soft-mode theory of surface reconstruction1 is used to calculate the surface Debye-Waller factor (SDWF) as a function of temperature near a supposed transition temperature (T0) between two reconstruction patterns. The soft surface mode gives rise to a sharp decrease in the SDWF as T0 is approached, suggesting that an examination the LEED Bragg intensities may help verify the soft mode theory. |
