Abstract

We compare inelastic electron tunneling measurements by Yamaguchi and Nishina for a GaSe thin slab with the surface projected total phonon density calculated by a linear-chain model fitted to recent inelastic atom scattering data of GaSe (001). We conclude that in case of relevant differences between bulk and surface-perturbed phonon densities only the latter can be significantly compared with inelastic electron tunneling spectra. Moreover, our previous observation that the dynamics of surface layers in GaSe is considerably different from that of the bulk is confirmed by a completely independent experimental technique.
