Opis:
In this work we investigate the conductivity in the basis plane of YBa$\text{}_{2}$Cu$\text{}_{3}$O$\text{}_{7-x}$ and Y$\text{}_{1-z}$Pr$\text{}_{z}$Ba$\text{}_{2}$Cu$\text{}_{3}$O$\text{}_{7-x}$ single crystals with a system of one-direction twin boundaries. The Pr dopants behave as efficient scattering centers of normal and fluctuating carriers. For this a slight doping with praseodymium (till z≈0.05) results in a significant narrowing of the temperature interval in which the pseudo-gap regime is realized in the ab-plane of YBaCuO single crystals.

Opis:
The effect of twin boundaries on the normal and fluctuating conductivity of ReBaCuO (Re = Y, Ho) single crystals was investigated. The results indicate that the Lawrence-Doniach theoretical model describes adequately the temperature dependence of the excess conductivity. The twin boundaries are efficient scattering centers for normal and fluctuating carriers. The derived values of the coherence length perpendicular to the ab-planeξ$\text{}_{c}$(0) are in good agreement with those obtained from magnetic measurements for stoichiometric YBaCuO crystals.

Opis:
Methods of modification of gate dielectrics of the MOS structures by high-field electron injection and arc plasma jet treatment were studied. It is possible to use them for correction of parameters, decreasing defects number and increasing reliability of MOS devices. It was found that the negative charge accumulated in the film of the phosphorus-silicate glass of the MOS structures with the two-layer gate dielectric SiO₂-phosphorus-silicate glass under the high-field electron injection can be used for modification of devices with the same structures. It is shown that the injection-thermal treatment allows to find and exclude MOS structures with defects of isolation and charge defects. Arc plasma jet treatment was found to improve characteristics of the MOS devices. These treatments increase injection and radiation resistance of the gate dielectric by creating the needed density of electron traps in the bulk of SiO₂ film.

Opis:
The influence of injection-thermal and plasma treatments on the characteristics of the MOS-structure is studied. It is shown that the thermal stable part of the negative charge which accumulates in the phosphorus-silicate glass (PSG) film in the structures with the two-layer gate dielectric $SiO_2$-PSG under high-field Fowler-Nordheim electron injection can be used for the characteristics modification of MOS-structures with above described structure. The injection-thermal and plasma treatments of MOS-structures are offered to use for improving the reliability and finding the samples which have the charge defects. It is found that using the injection-thermal and plasma treatments allows to increase the injection and radiation stability of the dielectric films of MOS-structures due to structural changes in the $SiO_2$ film and $Si-SiO_2$ interface.

Opis:
Methods to modify gate dielectrics of MIS structures by irradiation treatments and high-field electron injection into dielectric are considered. In addition, distinctive features of these methods used to correct parameters of MIS devices are studied. It was found out that negative charge, accumulating in the thin film of phosphosilicate glass (PSG) of the MIS structure having a two-layer gate dielectric SiO_2-PSG under the high-field injection or during the irradiation treatment can be used to correct the threshold voltage to improve the charge stability and raise the voltage of breakdown for the MIS devices. It is proved that the density of electron traps rises with the increasing thickness of the PSG film. In this paper a method to modify electrophysical characteristics of MIS structures by the high-field tunnel injection of electrons into the gate dielectric under the mode of controlled current stress is proposed. The method allows to monitor changing of MIS structure parameters directly during the modification process.

Opis:
Purpose The objective of this article is the analysys of methods for preventing and eliminating hydrates formations, classifying them and choosing the best ones for use in underground gas storage facilities. Comprehensive measures for the stable operation of gas storage facilities in the presence of conditions for the occurrence of hydrates formations were developed. Zones, being potentially prone to the hydrates formation during the gas storage facilities operation were identified. Design/methodology/approach The operational parameters of gas storage wells during gas withdrawal are analyzed. The identified wells were operated under difficult conditions due to the deposition of hydrates on the wellheads, in flowlines and process equipment of gas storage facilities. The places of the highest hydrates accumulation on underground gas storages were determined: from the bottomhole of wells to the gas purification unit of the gas gathering station. Hydrate-prone zones were identified by computational fluid dynamic (CFD) modeling at the location of regulating choke installations in underground gas storage facilities. Findings The zones of the greatest hydrates accumulation on underground gas storages were determined: from the bottomhole of wells to the gas purification unit of the gas gathering station. The analysis of the methods used in gas storage facilities of Ukraine to prevent and eliminate hydrates formation was out. A set of measures was proposed to prevent the hydrates formation in storage facilities to ensure their stable operation. Based on the Euler approach (Mixture model) by CFD modeling, zones prone to hydrates formation were determined at the installation site of regulating chokes in underground gas storages. The influence of the degree of fittings opening on the location of potential zones prone to hydrates formation was estimated. The gas-dynamic processes in the internal cavity of the gas pipeline at the installation site of the control fittings were studied and their influence on the distribution of bulk particles of the gaseous and liquid phases was established. Based on the studies performed, it was recommended to change periodically the mode of well operation for a certain time by opening or closing the regulating choke under favorable conditions for the formation of hydrates, especially at low ambient temperatures. Research limitations/implications The obtained results of experimental studies and calculations showed that in order to solve the problem of hydrates formation at gas storage facilities, it is advisable to use diverse measures through the introduction of modern intelligent systems for monitoring and controlling the technological process. Further refinement of the algorithm of the proposed monitoring and control system with its approbation in production was provided. Practical implications The results of the experimental studies and CFD modeling carried out allowed providing a more reasonable approach to the application of various available methods and measures to prevent hydrates formation in underground gas storage facilities. This approach made it possible to develop new effective ways and measures to prevent such complication. Originality/value Based on the conducted experimental studies and modeling, the major zones prone to hydrates formation in underground gas storages were determined. The developed measures will allow timely detection and prevention of hydrates formation at gas storage facilities are original.
