The effect of the adsorption Ba atoms with a thickness theta≤3-4 monolayers and implantation + ions an energy E 0 =0.5-2 keV on density states electrons in valence band, parameters bands, emission optical properties Ge(111) has been studied for first time. It is shown that during theta=1 monolayer, value thermoelectric work function φ decreases by ~ 1.9 eV, secondary electron coefficient quantu...

locus of control is said to affect learners' academic achievement. this effect has scarcely been examined within general english context. this study is concerned with examining the differences in general english (ge) course achievement among university students of humanities, sciences, and engineering. it also explores the effect of locus of control (loc) in ge course achievement among these th...

The interaction between organic (bio) molecules and semiconductor surfaces has been studied by several research groups for the development of applications in a variety of fields. In particular, recent studies on the interaction between semiconductor surfaces and amino acids have laid the foundations for understanding protein adsorption on semiconductor surfaces. Understanding the behavior of am...

The search of optimal structures magnesium germanide Mg 2 Ge under pressure has been performed using the software suite USPEX implementing evolution algorithm combined with density functional theory (DFT) approach. It is found that at pressures P≥15 GPa triclinic P1 and P-1, monoclinic P2 1 /c, orthorhombic Amm2 trigonal P3m1 can coexist besides well-known cubic Fm3m, Pnma hexagonal P6 3 /mmc o...

We present a review of our recent results for the comparative evaluation of the induced exchange interaction and quantum noise mediated by the bosonic environment in two-qubit systems. We report new calculations for P-donor-electron spins in Si-Ge type materials. Challenges and open problems are discussed.

Development of lift-off technique AlGaAs/GaAs- heterostructures, grown by the Metalorganic vapour-phase epitaxy, to GaAs carrier-substrate using silver-containing paste or Au-In compound has been carried out. Forming process frontal ohmic contact n-type conductivity based on systems Au(Ge)/Ni/Au and Pd/Ge/Au with specific resistance (2-5)·10 -6 Ω·cm 2 investigated. Analyzed was influence hetero...

a tellurium dioxide crystal is presented. The all-optical acousto-optic effect describes the combination of laser generated ultrasound with acousto-optic interaction. Laser generated ultrasound spectra are analyzed for tellurium dioxide using a 266 nm and a 1064 nm pulsed source, and used to characterize the acoustooptic interaction. The interaction is shown to be dominated by longitudinal acou...

Recent formulation of the Zaller model of mass opinion is generalized to include the interaction between agents. The mechanism of interaction is close to the bounded confidence model. The outcome of the simulation is the probability distribution of opinions on a given issue as dependent on the mental capacity of agents. Former result was that small capacity leads to a strong belief into random ...
