    Insulator-Metal transition: formation of Diamond Nanowires in n-type Conductive UNCD films

    Under normal process conditions UltraNanoCrystalline Diamond (UNCD) films are highly electrically insulating, but they can become highly conducting when Ar is substituted in the synthesis gas with some of N2. The...

    Synthesis of Nanocrystalline Diamond Films in Ar/H2/CH4 Microwave Discharges

    This work deals with the investigation of the microwave plasma assisted CVD process employed for nanocrystalline diamond (NCD) deposition, using an Ar/H2/CH4 feed gas. The different steps required in order to ins...

    Exchange Interactions and Curie Temperatures of 3D- and 2D-Ferromagnets

    Effective exchange interactions in bulk ferromagnets as well as in magnetic overlayers on Cu(001) covered by a Cu-cap layer of varying thickness were determined from first principles by map** of correspondin...

    Spin and charge transport in the presence of spin-orbit interaction

    We present the study of spin and charge transport in nanostructures in the presence of spin-orbit (SO) interaction. Single band tight binding Hamiltonians for Elliot-Yafet and Rashba SO interaction are derived...

    The influence of defects on electrical transport in magnetic multilayers

    The transmission matrix approach was used to evaluate the perpendicular magnetotransport in metallic multilayers on an abinitio level. The spin-polarized, surface Green function technique was employed within the ...

    Ab-initio theory of the CPP-magnetoconductance

    The current-perpendicular-to-plane (CPP) magnetoconductance of a trilayer consisting of a spacer sandwiched between two ideal leads is described on anab initio level. We employ the transmission matrix formulation...

    Interlayer exchange coupling: Preasymptotic corrections

    In the asymptotic limit, the interlayer exchange coupling decays as D −2, where D is the spacer thickness. A systematic procedure for calculating the preasymptotic corrections, i.e., the terms of order D −n with...

    Metal-organic deposition of YBCO and BSCCO platelets, films and wires

    Metal-Organic Deposition (MOD) technique has been used for the first time, in the spray version, to obtain thin and thick films of BSCCO on substrates like MgO and Ag and, in the dip** version, to deposit YB...
