We report on titanium contacts to n-type and p-type Si1ÿxÿyGexCy strained heteroepitaxial layers on (100)Si and material and electrical characterization of n-type and p-type platinum±silicide±germanide contacts to Si1ÿxÿyGexCy strained heteroepitaxial layers on (100)Si. Ti contacts to n-type Si1ÿxÿyGexCy show rectifying behavior at low doping levels but become ohmic as layers reach 10 cmÿ3. Ti ...

Cathode electrodes of the Si(Li) detector elements of the SIXA X-ray spectrometer array are formed by gold-palladium alloy contact layers. The equivalent thickness of gold in one element was measured by observing the characteristic L-shell X-rays of gold excited by monochromatised synchrotron radiation with photon energies above the L3 absorption edge of gold. The results obtained at 4 differen...
In the present work, we introduce a facile and reliable approach to decorate TiO2 nanotubes homogenously with wellseparated copper oxide nanoparticles. For this, we use a palladium-containing titanium alloy (commercial Ti 0.2 atom% Pd) and grow anodic, self-organized oxide nanotubes. Palladium is embedded in the tube wall during growth and acts as activator for a subsequent electroless copper-n...
inspired multi-objective optimisation algorithm Jun Chena, Mahdi Mahfouf, Gaffour Sidahmed, doi:10.1016/j.engappai.2014.08.014 Highlights • We model mechanical properties of heat treated alloy steel using interpretable fuzzy models. • We demonstrate how to locate the ‘best’ processing parameters and chemical compositions. • We demonstrate how to achieve certain mechanical properties. • We demon...
Single-crystal aluminum-gallium oxide films have been grown by molecular beam epitaxy in the corundum phase. Films of the (Al(1-x)Ga(x))(2)O(3) alloys doped with neodymium have favorable properties for solid-state waveguide lasers, including a high-thermal-conductivity sapphire substrate and a dominant emission peak in the 1090-1096 nm wavelength range. The peak position is linearly correlated ...
We present a first principles study of the magnetoresistance (MR) perpendicular to the planes of atoms and the interlayer exchange coupling (IEC) in Fe/Si/Fe trilayers. In both cases the dependence on the number of spacer layers is investigated, whereby the spacer thickness ranges between 3 and 21 Å for the IEC and extends to 33 Å for the MR in order to obtain the asymptotic behavior. Additiona...
Post-deposition rapid thermal annealing (RTA) was performed on the Cr-less Co20at%Pt alloy with a Mn diffusion layer on top. A value of about 8 10 erg/cm3 was obtained for the as-deposited film and it decreased only up to about 10% after annealing. The high intergranular exchange coupling of the as-deposited CoPt film was suppressed by RTA and the coercivity increased dramatically from about 22...
We have performed a high-resolution synchrotron radiation photoelectron spectroscopy study of the initial growth stages of the ZnPd near-surface alloy on Pd(111), complemented by scanning tunnelling microscopy data. We show that the chemical environment for surfaces containing less than half of one monolayer of Zn is chemically distinct from subsequent layers. Surfaces where the deposition is p...
