Analyzed on the example of CdTe are formation and propagation of shock waves during pulsed laser irradiation of a solid surface. It is shown that before the appearance of a shock wave in a solid, a gradual increase in pressure gradient leads to formation of dislocations, density of which increases with depth. The dislocation density is maximum at the place of shock wave formation.

The effect of low-temperature annealing on light emitting properties of naSi/SiOx porous column-like nanocomposite films has been studied. Influence of type of chemically active gas or inert ambient on PL characteristics is shown. Existence of metastable defects in such structures is shown. A temperature interval for healing the metastable defects is defined. Mechanisms to reduce a non-radiative recombination channel depending on the gas ambient are proposed.

Shown in this work is the possibility to create industrial technology for production of solar cells FTO/CdS/CdTe. The technology includes annealing in freon processing step for activation of cadmium telluride base layers deposited by thermal vacuum evaporation. Solar cells with efficiency of 7% have been obtained. Structural and morphological researches allowed to identify interrelation between photovoltaic characteristics and features of the recrystalization process in base layers after annealing in freon as compared with the standard chloride treatment.

The theoretical comparison of possible response measurement techniques for a biosensor based on localized surface plasmon resonance (LSPR) in spherical Au nanoparticle was made. The methods for measuring LSPR response considered differed in the treatment of the change of light extinction spectrum along the wavelength and extinction coordinate axes upon the formation of dense biomolecular monolayer on the surface of the sensitive element. In addition, the transformation of the extinction LSPR band with increase of the nanoparticle radius from 5 to 125 nm was investigated towards the optimization of LSPR response for dipolar and quadrupolar LSPR extinction peaks. A novel method for the measurement of wavelength shift Htop⁺ was introduced and demonstrated to be more effective for estimation of the LSPR biosensor response as compared to commonly measured extinction peak shift Δλmax .These techniques were proved to produce maximal LSPR response when large-size Au nanoparticle (with a radius of 125 nm) was used as a sensitive element of biosensor. The preferable mode of extinction difference measurement turned out to be Vright, which is carried out at a wavelength of the extreme extinction spectrum derivative on a right slope of the LSPR peak. For this method, optimal nanoparticle radii were found to be about 40 nm for the dipolar LSPR peak and near 100-105 nm for the quadrupolar one.
