The Surface Photoelectric Effect
Physical Review, 1949An expression is derived for the photoelectric current produced at the surface of a metal, the conduction electrons being supposed free and the potential barrier of arbitrary shape. The validity of the common assumption that the current arising from conduction electrons of a particular momentum can be expressed as the product of an excitation function ...

Journal of Applied Mathematics and Mechanics, 1999
The author studies the waveguide properties of one-dimensional periodic surfaces and interfaces. It is established that all surfaces, on which the Neyman condition is satisfied, possess the wave property, namely, they are waveguides. The existence of a region of missing the frequences localized in zero neighbourhood is called the phenomenon of ...

Effect of surface tension on alveolar surface area
Journal of Applied Physiology, 2002At fixed lung volume (Vl), alterations in surface tension change alveolar surface area (S) and lung recoil (Pl). Wilson (26), using data from fixed lungs (1, 9), quantified the isovolume change in S with Pl. We reexamined this question in fresh excised rabbit lungs, with two important differences.

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.

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.

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 sulphidation reactions
Canadian Metallurgical Quarterly, 1990AbstractPure iron and an Fe–41 wt% Ni alloy are reacted at temperatures in the range 793–1073 K with H2–H2S–N2 atmospheres corresponding to equilibrium P S2 levels from 6.5 × 10−5 to 0.65 Pat The kinetics of iron sulfidation are intermediate in form to linear and parabolic rate laws.

Effects of pH on the Dentin Surface
Journal of Esthetic and Restorative Dentistry, 1992Amicroleakage and scanning electron microscope (SEM) study was conducted in order to investigate the effects of acidic primers on prepared dentin surfaces. The microleakage study revealed that no significant differences were noted between the five materials tested in regard to leakage at enamel and dentin margins.

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.

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.
