Activation of a semiconductor surface by a pulsed magnetic field

Abstract. The long-term transformations of photoluminescence of GaP, GaAs and InP single crystals treated with pulsed weak magnetic fields are obtained. The treatments were performed in two regimes, namely, single-pulse (τ = 30 ms) and multi-pulse (τ = 1.2 ms) ones, at varying magnitudes of magnetic induction. The defect structure transformations were inferred from the radiative recombination spectra in the 0.6-2.5 μm at 77 K. A possible mechanism of observed modifications related to the electron spin transformation is discussed.

“…Let us dwell on this point in more detail. It is known from literature [9,10] that, in addition to the process of chemical bond breakage in point defect complexes, magnetic field also stimulates the processes of adsorption and gettering the impurities on MTactivated surface.…”

Abstract. The effect of static magnetic field (B = 0.17 T) on composition of defects and lifetime of charge carriers in solar silicon crystals has been investigated. Studied in this work was the character of changes in electrical characteristic of solar silicon. These changes are dependent on the time elapsed after the magnetic treatment. The results have been discussed in terms of spin-dependent processes in the subsystem of structural defects.

Formation of nanostructured state in LaBGeO5 monolithic glass using pulsed magnetic fields

A.S.¹

2016

Abstract. Using the methods of transmission electron microscopy, X-ray structure analysis and thermal differential analysis, it has been discovered that the pulsed magnetic field (PMF) intensifies homogeneous crystallization in LaBGeO 5 -glass system, promotes homogenization of crystalline phase distribution inside the bulk of glass matrix. A possibility of obtaining the volume nanostructured state in LaBGeO 5 -glass due to application of PMF has been suggested and experimentally grounded.
