Theoretical Background of Interfaces and Multilayers
The considerable progress in material technology has made possible the fabrication of stratified crystals with widely adjustable geometrical parameters . It is generally stressed that the availability of such materials opens the way to condensed-matter physics with reduced dimensionality where quantum size effects become dominant. One thinks of course primarily of the behavior of electrons in these sharp multilayer structures, for which these quantum size effects typically appear between 10 to 1000 Ã in most studied materials. It should be emphasized, however, that all kinds of waves traveling through multilayer structures will be influenced by the stratification of the medium, possibly for other geometrical sizes than those considered for electrons. Photons propagating in heterostructures are not the least interesting of these wave phenomena, from the point of view of the applications.
