Abstract

The surface Debye temperature and the vibrational dynamics of Sb(111) were studied using helium atom scattering. The Debye–Waller attenuation of the elastic diffraction peaks was measured at surface temperatures between 98 K and 447 K. A surface Debye temperature of (155 ± 3)K is obtained within the description originally derived for electron diffraction. The attractive well depth for the He–Sb(111) interaction is determined to be (4.5 ± 0.5) meV. The perpendicular mean-square displacement for the surface at room temperature is estimated to be (1.8 ± 0.4) × 10− 2Å2.
