DESCRIPTION:The study of semimetal surfaces including those of various top
 ological insulators represents a new wide territory of investigation for h
 elium atom scattering. \nOwing to the nature of the He-surface scattering 
 process\, inelastic scattering intensities convey direct information on th
 e electron-phonon (e-p) coupling strength of these surfaces. As a conseque
 nce of the e-p coupling helium scattering can observe subsurface phonon mo
 des which can even be localized several layers beneath the surface.\n
