Surface Structure of Bi(111) from Helium Atom Scattering Measurements. Inelastic Close-Coupling Formalism
Elastic and inelastic close-coupling (CC) calculations have been used to extract information about the corrugation amplitude and the surface vibrational atomic displacement by fitting to several experimental diffraction patterns. To model the three-dimensional interaction between the He atom and the Bi(111) surface under investigation, a corrugated Morse potential has been assumed. Two differen...
متن کاملHelium-surface interaction potential of Sb(111) from scattering experiments and close-coupling calculations
Helium atom scattering (HAS) was used to study the antimony Sb(111) surface beyond the hard-wall model. HAS angular distributions and drift spectra show a number of selective adsorption resonance features, which correspond to five bound-state energies for He atoms trapped in the surface-averaged He-Sb(111) potential. As their best representation, a 9-3 potential with a depth of 4.4 ± 0.1 meV wa...
متن کاملMode-selected electron-phonon coupling in superconducting Pb nanofilms determined from He atom scattering.
The electron-phonon coupling (EPC) strength for each phonon mode in superconducting Pb films is measured by inelastic helium atom scattering (IHAS). This surprising ability of IHAS relies on two facts: (a) In ultrathin metal films, the EPC range exceeds the film thickness, thus enabling IHAS to detect most film phonons, even 1 nm below the surface; (b) IHAS scattering amplitudes from single pho...
متن کاملPhonon lineshapes in atom-surface scattering.
Phonon lineshapes in atom-surface scattering are obtained from a simple stochastic model based on the so-called Caldeira-Leggett Hamiltonian. In this single-bath model, the excited phonon resulting from a creation or annihilation event is coupled to a thermal bath consisting of an infinite number of harmonic oscillators, namely the bath phonons. The diagonalization of the corresponding Hamilton...
متن کاملFinite Debye-Waller factor for "classical" atom-surface scattering.
We consider atom-surface scattering at low surface temperature, fixed incident energy and fixed interaction potential. We examine the limit as the mass m of the incident particle -oc, and thus its de Broglie wavelength --* 0. We show that in this "classical" limit, the Debye-Waller factor (a quantum effect) for the strictly elastic scattering amplitude tends to a finite limit. We propose scatte...
