Effects of surface roughness on surface polaritons
Physical Review B, 1979We have studied the effect of surface roughness on the behavior of surface polaritons in samples of GaP by means of Raman scattering. The roughness of the surfaces of thin-slab samples (\ensuremath{\approx} 15 \ensuremath{\mu}m thickness) was controlled by the size of the final polishing powder and by etching and annealing.

Effect of Surface Roughness on Surface Photochemistry
MRS Proceedings, 1994AbstractPhotoinduced processes on surfaces is of fundamental importance in materials processing. For example, photo-assisted chemical vapor deposition has been used to deposit a number of different materials on solid substrates. The effect of substrate morphology on photoinduced processes can be an important factor in film growth.

Surface dyslexia: A regression effect?
Brain and Language, 1985Although the disorder of acquired surface dyslexia is considered as a pathological syndrome in the psycholinguistic and neuropsychological literature, it may also be conceived of as part of a general regression in functioning consequent upon brain damage.

Surface effects in invasion percolation
Physical Review E, 1997Boundary effects for invasion percolation are introduced and discussed here. The presence of boundaries determines a set of critical exponents characteristic of the boundary. In this paper we present numerical simulations showing a remarkably different fractal dimension for the region of the percolating cluster near the boundary.

Surface States, Surface Effects
1995It has been stated already that PES, because of the small escape depth of the electrons in a solid, in principle, is a surface sensitive technique. However, the agreement found in the preceding chapter between calculated and experimental bulk band structures was remarkable.

Surface effects in metal microclusters
Physical Review B, 1987The interatomic distances encountered in metal microclusters are calculated by assuming that the phenomenon of multilayer relaxation observed on macroscopic surfaces applies also to the surfaces of finite polyhedron-shaped clusters. The calculations of surface relaxation values are done by means of the modified point-ion model developed by the authors.

Surface Effects and Surface Devices
1987The preceding chapters have concentrated on the structure and properties of several semiconductor devices. Up to now, contacts to the outside world have at all times been considered as ideal; that is, they do not in any way affect the operation of the device. This is normally not the case.

The effect of surface on melting point
Journal of Colloid Science, 1948Abstract The macroscopic nature of fusion in extended systems is discussed in detail. In this connection, the experimental significance of the term “melting point” is examined. A relation between the extent of surface and internal pressure is derived. The new relation is to be distinguished from Kelvin's formula which relates the pressures on either

Surface polarization and flexoelectric effect
Journal of Applied Physics, 1991In order to evaluate the order of magnitude and to establish the origin of the surface polarization, experimental investigations of direct piezoelectrical effect in nematic liquid crystals have been performed. The experimental setup used allows the temperature dependence of the electrical response of a nematic sample, submitted to periodic acoustic ...

The Effects of LASIK on the Ocular Surface
The Ocular Surface, 2004Laser in situ keratomileusis (LASIK) can affect corneal sensation, aqueous tear production, wound healing, and the incidence of corneal erosions. Virtually all patients experience dry eye at least transiently after LASIK. Because intact corneal sensation drives tear production, denervation associated with the LASIK procedure is the most significant ...
