Energy transfer coefficient (analogue of LDOS) and aperiodicity index are defined to characterise the nonlinear response and the surface resonances in a thin layer separated from the underlying bulk crystal by an anharmonic interface. Regions of periodic, aperiodic and intermittent motion of the system are found by analysing the electric circuit obeying the same delayed differential equations. (C) 2002 Elsevier Science B.V.
