Abstract

The interest in the dynamics of surfaces and overlayers on surfaces has recently intensified. This is largely due to the development of new, more detail-yielding, experimental techniques [1] and the investigation of new materials. The complexities inherent in these systems have hindered the development of a clear theoretical understanding of their dynamic behavior. The simultaneous occurrence of nonlinear interaction laws, incommensurabilities, disorder due to pinning effects and the resulting complexity of the excitation spectra did not favor a simple analytical approach [2]. We present here the results of a molecular dynamics study. This numerical method, coupled with a simple, but very effective, Fourier transformation allowed us to investigate this complicated problem without further approximations.
