The electronic band structure, the local densities of states (the total and layer-resolved ones), and the distribution of charge density of valence electrons at the (111) polar surface in A3B5 and A2B6 crystals, such as GaAs and ZnSe, have been studi

Influence of Y₂O₃ nanoparticles on sintered iron structure and microhardness is investigated. Ferrite grain growth is shown to be slowed down by the clusters which cause altering the grain shape from needle-like to equiaxial (with lower specific

Considered in this paper is the effect of electron irradiation on the phasestructural state and micromechanical characteristics of reactively- and nonreactivelypressed TiB₂–TiС composite ceramic materials. It is shown that reactively-pressed spe

We studied the effect of neutron irradiation on composite material HfC-HfB₂- C made using rapid reactive hot pressing technology. The histograms of microhardness and results of X-ray phase analysis, obtained both before and after neutron and electr

Microhardness variations in germanium crystals caused by a weak constant magnetic field have been studied. It is fount that the magnetomechanical effect, that is relative change in microhardness, becomes relaxed in time. The results obtained indicate

The magnetoresonance influence as well as the micrawave superhigh-frequency (SHF) magnetic field effect on the microhardness of silicon crystals has been studied. It is established that the action of SHF field results in decreasing microhardness, whi

IR spectroscopy study is indicative of the change in the relative concentration of interstitial oxygen in silicon monocrystals after their treatment by using the magnetic field. This is an evidence of a considerable effect of magnetic field on the de
