0031-9007= We propose and investigate the properties of a digital ferromagnetic heterostructure consisting of a -doped layer of Mn in Si, using ab initio electronic-structure methods. We find that (i) ferromagnetic order of the Mn layer is energetically favorable relative to antiferromagnetic, and (ii) the heterostructure is a two-dimensional half-metallic system. The metallic behavior is contr...

abstracthydroforming process is a deep stretching process only with the difference that a fluid is used instead of the mandrel. this paper investigates the hydroforming process of non-cylindrical and non-spherical geometries using finite element analysis software to calculate the influences of effective process parameters such as the coefficient of friction between the surfaces and the pressure...

We present a flexible approach to transfer metallic photonic crystals (MPCs) onto end facets of optical fibers. The MPCs were initially fabricated on a glass substrate with a spacer layer of indium tin oxide (ITO), which was used as a buffer layer in the transferring process. The fiber ends were firstly welded on the top surface of the MPCs by a drop of polymer solution after the solvent evapor...

double layer zno/sno2 thin film resistive gas sensors were fabricated by successive pvd of those oxides onto porcelain substrates. the metallic contacts were provided by electron beam evaporation of platinum onto substrates prior to deposition of the gas sensitive layers. deposits were thermally annealed at different temperatures. it was shown that the activation energy of electrical conduction...

When a single-layer graphene sheet is contacted with metallic electrodes, tunnel barriers are formed as result of the doping by metal in contact region. If Fermi energy level modulated gate voltage, phenomenon Klein tunneling results specific features conductance and noise. Here we obtain analytically exact solutions for transmission reflection probability amplitudes using trapezoidal potential...

A shear-induced structure (SIS) is formed under appropriate concentration and shear conditions in a surfactant micellar solution. In this study, we performed experiments of solution dosing fully developed two-dimensional turbulent channel flow from sintered metallic wire mesh plate attached to side wall. We investigated the behavior elongation during its passing through strong due flow. It was ...

A new multi-layer substrate integrated waveguide (SIW) structure is developed to design dual-band evanescent-mode band-pass filters (BPFs). Two independent series LC circuits are implemented by incorporating metallic irises in the different layers of the structure. The combination of the metallic irises with capacitive-plates is embedded inside the SIW to independently excite two evane...

We propose a novel approach to fabricating flexible transparent metallic grid electrodes via evaporative deposition involving flow-coating. A transparent flexible metal grid electrode was fabricated through four essential steps including: (i) polymer line pattern formation on the thermally evaporated metal layer onto a plastic substrate; (ii) rotation of the stage by 90° and the formation of th...
