    Ab-initio calculations of spin tunneling through an indirect barrier

    We use a fully relativistic layer Green's functions approach to investigate spin-dependent tunneling through a symmetric indirect band gap barrier like GaAs/AlAs/GaAs heterostructure. Our calculations show clearly that the appearance of energy windows with significant spin polarization depends mostly on the location of transmission resonances and their corresponding zeros and not on the magnitude of the spin splitting in the barrier.

    Properties of CuInX2 (X=S, Se, Te) chalcopyrite-structure compounds.

    We present results for band structure, density of states, and the imaginary part of the frequency-dependent linear and nonlinear optical susceptibilities for CuInX2 (X=S, Se, Te) chalcopyrite-structure single crystals. We find that these crystals are semiconductors with direct band gaps, and have calculated their birefringence and frequency-dependent complex second-order non-linear optical susceptibilities.

    We report on the synthesis, crystal structure and infra-red, Raman and NMR spectra of 2, 4, 4- trimethyl-4, 5- dihydro-3H-benzo[b] [1, 4] diazepin-1-ium tetrachlorocadmate, [C12H17N2]2CdCl4 and benzene-1,2-diaminium decachlorotricadmate(II) [C6H10N2]2Cd3Cl10.
