Chapter 3 - Phonons in supported layers
Résumé
This chapter is on phonons in supported slabs. It starts by a presentation of the general equations for an elastic material. General analytic expressions are obtained for bulk and surface Green’s functions, as simple examples of the continuous interface response theory of Chapter 1 of this book. With the same coherent approach, many analytical results are presented for resonant guided elastic waves in an adsorbed slab and in an adsorbed bilayer on homogenous substrates. The case of an adsorbed layer on a one-dimensional phononic crystal is also considered. Finally the relation of these results with some experiments, such as Raman and Brillouin light scattering, are discussed.
