    Description / Table of Contents: The Germination of Seeds, Third Edition contains the same content in the previous edition, but with modifications in each section, containing updated information. As the first two editions, this edition attempts to treat critically the available information on seed germination and to assimilate this information. This text first discusses the structure and chemical composition of seeds. This book then explains germination and related concepts, such as factors affecting this process, inhibition and stimulation, and seed metabolism. This selection concludes by explaining the ecology of germination. This publication will be invaluable to those in the field of agriculture, as well as students and layperson interested in seed germination.

    Notes: The performance of organic light emitting devices is strongly dominated by the cathode materials, because the injection barrier for electrons is largely affected by the electronic properties of the used metal. We report internal photoemission measurements of the barrier height existing between aluminum tris(8-hydroxyquinoline) and different cathode materials. It is shown, that a linear relationship exists between the measured barrier height and the work function of the cathode material. However, the gradient in this phenomenological equation indicates, that the barriers cannot be calculated as usual merely as the difference of the lowest unoccupied molecular orbital of the organic material, and the work function of the cathode, but that surface states play an important role. The barrier height remains unchanged after storage, even though the contact exhibits clearly visible degradation effects and numerous "dark spots." © 1999 American Institute of Physics.

    Notes: The presence of an interface strongly affects the attenuation of surface-acoustic waves due to coupling to temperature fluctuations via the thermoelastic effect. This is demonstrated for Rayleigh waves propagating in a substrate coated by a thin film with thermal conductivity and heat capacity different from those of the substrate. Even if the thickness of the film is so small that its effects on the frequency and displacement field are negligible, the attenuation coefficient of the surface wave can be strongly enhanced.

    Notes: An elastic medium that occupies the region x3(approximately-greater-than)ζ(x1), where the surface-profile function ζ(x1) is assumed to be a stationary, stochastic process, is studied. The displacement field u(x;t) in this region is assumed to satisfy stress-free boundary conditions on the surface x3=ζ(x1). First the boundary conditions satisfied by the mean displacement field 〈u(x;t)〉 on the plane x3=0 are obtained, where the angle brackets 〈 〉 denote an average over the ensemble of realizations of ζ(x1). The results are then used to obtain the dispersion relation for surface acoustic waves of shear horizontal polarization propagating in the x2 direction, i.e., parallel to the grooves of the random grating defined by the surface-profile function ζ(x1). It is found that the surface acoustic waves of this polarization, which cannot exist on a planar, stress-free surface of an elastic medium, are trapped by the random roughness, but are bound to the surface for only a finite range of values of the wave number k2 characterizing their propagation in the x2 direction. The attenuation of these roughness-trapped surface acoustic waves is also determined.

    Notes: In this paper the propagation of surface acoustic waves along the grooves of a periodically corrugated surface is studied. It is shown that in addition to a surface acoustic wave of predominantly sagittal polarization, which corresponds to the Rayleigh wave, an additional surface wave exists which is of predominantly shear horizontal polarization. While the former remains localized at the surface for arbitrarily short wavelengths, the latter has a limited range of existence. The dispersion curves of these surface waves are calculated numerically for a shallow sawtooth grating.

    Notes: We recently demonstrated that insulating surface impurity phases in high-temperature superconductors can be detected by thermally stimulated luminescence. Moreover, we suggested that the intensity of luminescence is related to the magnitude of the rf surface resistance. In this work we show that a quantitative correlation exists between these two quantities, and that luminescence can be a very useful technique for estimating rf surface resistance.

    Notes: We present three-dimensional simulations of field emission from open and capped (5,5) carbon nanotubes, with consideration of hydrogen saturation of the open structure. The transfer-matrix methodology used for the calculations reproduces appropriate band-structure effects due to the periodic repetition of a basic unit of the nanotubes and the use of Bachelet pseudopotentials. The total-energy distributions of field-emitted electrons contain peaks, which are related to standing waves in the shell of the nanotubes and to resonant states at the apex of the closed structure. These peaks move to lower energies with increasing electric field. The results indicate that field emission is more efficient with the open structure and that hydrogen saturation of the dangling bonds results in a further enhancement of the current.© 2001 American Institute of Physics.
