Laser-induced deposition of nanostructured copper microwires on surfaces of composite materials

Microelectronics industry is growing fast and the rate of new devices’ development increases every year. Therefore, methods for simple and high-precision metal coating on dielectrics are needed. Existing methods do not allow performing the high-precision metal deposition without using photomasks, while making photomask for each prototype is long and expensive process. One of the methods of maskless metal deposition is laser-induced chemical liquid-phase deposition (LCLD). In this work we show the effect of substrate surface type on a result of LCLD. Deposited copper structures were characterized by SEM, EDX and impedance spectroscopy. The results show that laser-induced copper deposition is highly affected by the surface being homogeneous or composite material. It was found that the deposits with low resistivity and high quality metal localization mostly appear on the two-phase surfaces. In contrast, deposits on one-phase surfaces exhibited poor topology of copper material.

Control of the phase composition of nanostructured silver iodide

Problems concerning the choice of synthesis technique and criterion that can be used to estimate the role of random factors in the formation process of nanosystems are discussed. Control of the nanostructured silver iodide phase composition is achieved by thermal modification. As the initial material we use AgI nanopowder obtained by an exchange reaction of aqueous solutions of AgNO3 and KI. The morphology of the surface of the samples has been studied using scanning electron microscopy. The phase composition is determined by X-ray phase analysis. The modification of the initial material has been carried out simultaneously with differential thermal analysis. Particular attention is paid to the entropy of the control, which characterizes the role of random factors by synthesizing nanosystems.

On the Possible Existence of Vitreous Solid Electrolytes with a Molten Cationic Sublattice

A phenomenological justification is proposed for the model of a molten cationic sublattice. The minimum ionic conductivity of the vitreous solid electrolyte is estimated. Special emphasis is given to the problem of interaction between the cationic and anionic sublattices in the course of ion transfer.

On the Evaluation of the Effectiveness of the Journal Fizika i Khimiya Stekla (Glass Physics and Chemistry)

This paper reports on the results of calculating the standard impact factor K for the journal Fizika i Khimiya Stekla (Glass Physics and Chemistry) in comparison with the standard impact factor for other Russian journals. Modern methods for evaluating the effectiveness and scientific popularity of periodical editions are discussed. It is demonstrated that glasses are nanostructured condensed materials formed from medium-range order nanofragments. This determines the urgency of the “glass subject matter” and the high rating of the journal Fizika i Khimiya Stekla (Glass Physics and Chemistry).
