The atomic ordering of the amorphous diamond-like carbon at the scale larger than short-range order is directly related to the characteristics of the array of interstitial voids. The large interstitial voids are responsible for the first diffraction

Blanks - the thin quartz plates industrially used for oscillators, nowadays produced at rates of millions per week - need thorough controls of their properties. The most important of them, the correct orientation of the plates' surface relative to ce

The crystals with a continuous change in lattice constants (delta-crystals) can be used in X-ray optics since they are able to change the divergence of X-ray beam. The samples of linear (one-dimensional) delta-crystals of potassium-rubidium biphthala

The investigation of crystal growth kinetics and phase equilibria in the system K 2 SO 4 -K 2 CrO 4 -H 2 O was carried out using the method for the determination of the saturation temperature and the growth rate by microscopic observation of the seed

Recently a Monte Carlo simulation model has been developed that calculates the atom pair energy by the convolution integral of the potential field of atoms, molecules or atom clusters. This model is used here to calculate structures of sulfur molecul

The description of a goniometer for the rapid automatic sorting of round quartz blanks, commercially used as oscillator plates, is presented. Local variations of the cutting angle (i.e. the angle between a suited lattice plane and the AT-cut surface)

The application range of the /spl Omega/-Scan method and the existing SC machine can be essentially extended by reducing the restrictions given by the measuring arrangement and the precision demands. For the not included orientations, other reflectio

Recently developed angle-sorting machines for AT-cut quartz based on the /spl Omega/-Scan method allow the measurement of small blanks down to about 1 mm/sup 2/, the position-dependent measurement of wafers, as well as the determination of absolute c

The influence of the Cr/Au multilayer electrode structure on the electrical parameters of AT-cut quartz resonators was investigated and the results are discussed. Using the Ballato's exact transmission-line analogs applied to a finite plate with non-

An adjustment method for bars before cutting which uses the properties of X-ray three-beam diffraction is described. This procedure avoids two types of cutting errors: miscuttings of the delivered bars and misalignments of the bars on the holder. How
