Ellipsometry of rough surfaces
Applied Optics, 1980Ellipsometry measurements on several different kinds of rough surfaces were compared with stylus measurements of the surface texture. For steeply sloped periodic surfaces, the ellipsometric angles Delta and psi varied rapidly as the angle of incidence was varied near a diffraction minimum. This effect is interpreted in terms of the Kirchhoff theory and

Abstract A summary of the theoretical and computational approaches to rough surface scattering is presented. For the Dirichlet problem new computational results are presented for the behaviour of the normal derivative of the field on the surface as well as the behaviour of coherent and incoherent intensities as a function of angle and surface height ...

Abstract When two surfaces are brought into contact, they first touch where the summits of the surface asperities make contact. Consequently, surface roughness or topography strongly influences those physical phenomena associated with contact: friction, adhesion, and wear.

Ultrasonic measurements of surface roughness
Applied Optics, 1992We describe the use of pulsed ultrasound at MHz carrier frequencies to reflect and scatter from rough surfaces in an analogous way that light is used, comparing the results to stylus data. A principal application is to the manufacturing environment for on-line real-time sensor feedback and process control.

Surface polarons near rough surfaces
Physical Review B, 1989L'hamiltonien effectif du polaron est obtenu a l'aide de la transformation unitaire de Lee-Low-Pines et en considerant le deplacement des electrons dans le champ instantane des phonons optiques. On effectue des calculs numeriques du potentiel d'image du polaron et de sa masse effective, a partir d'une surface de ZnO (a gradins dans les cas ou le ...
