Continuum Elastic Theory for Dynamics of Surfaces and Interfaces Continuum elastic theory remains a valuable tool of modern condensed matter physics. Step induced phonons at vicinal surfaces.
Elastic theory is used to obtain the vibrational density of states at a stepped surface.
Step induced phonons appear as peaks in the surface density of states. Adsorbate vibrational relaxation. Elastic theory is used to study damping of low-frequency adsorbate vibrations via resonant coupling to the substrate phonons. Our theory provides a general expression for the vibrational damping rate which can be applied to widely varying coverages and arbitrary overlayer structures. Guided elastic waves in thin films.
