Complete plane

Let us assume that the constituent units of both a crystal and that of growth are simple cubes. This kind of model crystal is called a Kossel crystal, and is shown in Fig. 3.9. The 100 face is completely paved by the unit, and the surface is atomically flat. This face is called the complete plane. The 111 face, however, consists of kinks, as can be seen in Fig. 3.9, and has an uneven surface, and so it is called an incomplete plane. In contrast to [111], [110] corresponds to a face consisting entirely of steps. Kossel did not give a particular name to this t3TJe of crystal face. 

In diphenylamine and finally triphenylamine the basicity is still lower, so that this last amine only forms salts with the strongest acids of all, such as HC104. A condition for maximum resonance is a completely plane structure, which can, however, not be satisfied in the last-mentioned substance. This is also the case with dimethyl 0-toluidine, which is a weaker base than dimethylaniline, while 0-toluidine has practically the same strength as aniline. 

Film thickness is determined by the intensity of the reflected light [56,87,88]. This determination can be combined with the measurement of Bruster s angle dB, i.e. the angle at which the white light (non-polarised light) and the reflected light is completely plane-polarised (Fig. 2.14). 

On the other hand, the Gibbs free energy function is defined as G = U+ PV - TS from Equations (104) and (124), which may be expressed as, dG = dU + PdV + VdP - TdS -SdT, and the excess Gibbs free energy, Gs, of the interfacial region in a reversible process, for a completely plane interface can be expressed as... 

Innovations range from individual parts to the complete plane. There is the armored flight deck door to help secure flight decks. The one-inch thick door includes an RP sandwich structure using a phenolic honeycomb core between phenolic-glass fiber laminated facing sheets. 

If the lateral growth mechanism is relatively rapid, the rate of formation of the new nuclei on the completed planes will be the decisive factor in controlling the overall growth rate. 

Early experimenters with x-radiation [1,9] noted that x-rays could be polarized like other forms of electromagnetic radiation. Barkla [9] showed that the primary bremsstrahlung radiation was partially polarized. A later investigator, Ross [10], showed that at the high-energy limit of the white spectrum, the x-ray photons were very nearly completely plane polarized. This is in sharp contrast to primary characteristic x-rays, which are unpolarized. 

A scattering process will also result in polarization of x-rays according to the classical Thompson theory expressed by Eq. (2.1). For an unpolarized primary beam, scattering at an angle (26) of 90° results in nearly complete plane polarization of the scattered x-rays. Thus, crystal diffraction of x-rays produces plane-polarized radiation. If the diffraction angle (26) approaches 90°, polarization becomes nearly complete. 

As mentioned above in the context of the Prank-Read source, dislocations can also be annihilated. A simple example are two opposite edge dislocations moving on the same slip plane. As explained in section 6.2.7, the superposition of their stress fields causes an attraction. If they approach, the additional upper and lower half planes can unite and form a complete plane, causing the dislocations to vanish.
