First-principles method has been used to study the intrinsic brittlement of Mo3Si. The crystal constants, formation energy, cohesive energy, electronic structure, elastic constants of Mo3Si were calculated. The results were in good agreement with experiment data. Electronic structures showed that the strong covalent bonding between the nearest neighbour Mo atoms, which arrange perpendicularly each other, leads to embrittlement of Mo3Si.

The methods of the theory of the functional of electron density and pseudopotential from the first principles btained the characteristics of an electronic subsystem of the RRAM (Resistive Random Access Memory) layer constructed on the basis of epitaxial films Si0.9Ge0.1 with dislocations and embedded in them silver atoms. The spatial distributions of the density of valence electrons and their cross sections within the cell, the distribution of the density of electronic states, and electric charges in the vicinity of the silicon atoms in different atomic environments are calculated. It is investigated how changes in the electronic subsystem of investigated objects influence the change of their properties from non-conducting to conducting ones.

The effect of strain on the band structure of the GeH monolayer has been investigated by first-principles calculations based on density functional theory. The results show that the change of the band gap under the zigzag strain, the armchair strain and the biaxial strain is nonlinear. The effect of the biaxial strain on the band gap is the most obvious. In addition, the changes of energy under the three kinds of strain are asymmetric and the biaxial strain make the energy change the most. This work has significant implication of strain to tune optical catalytic properties of GeH monolayer.
