Anisotropic electrical resistivity during annealing of oriented columnar titanium films

We report on the evolution of anisotropic electrical resistivity versus temperature of titanium thin films. An oriented titanium film (1 μm thick) is sputter deposited by GLancing Angle Deposition (GLAD) using an incident angle α = 80° of the particle flux. Two parallel Ti electrodes cover this GLAD film. We measure the components of the conductivity tensor by the van der Pauw method during an ...

Anomaly of the electrical resistivity of polyvalent metal films with additions of Mn (and Fe)

2014 Polyvalent metal films with dissolved magnetic additions are produced by quench condensation onto a substrate held at 10 K. The films are subsequently annealed at higher temperature Ta. The electrical resistance is measured below Ta. The alloys In + 1 at % Mn, Pb + 0.8 at % Mn and Pb + 2.4 at % Fe do not show a resistance minimum. The resistance of Sn + 0.2 at % Mn and of A1 + 1 at % and 2...

Role of volume versus defects in the electrical resistivity of lattice-distorted V(001) ultrathin films

4 nm thick V layers grown by triode sputtering on MgO 001 single crystals and capped with MgO exhibit a perfect epitaxy accompanied by a tetragonal distortion and an unexpected volume compression that increases with the V deposition temperature. The electrical resistivity follows a deposition temperature dependence with these structural modifications, decreasing by an order of magnitude across ...

Effect of surface bond-order loss on electrical resistivity of metallic polycrystalline thin films

The effect of surface bond-order loss on the classical resistivity of metallic polycrystalline thin films is studied. The potential barriers due to grain boundaries considered here contain square-well depressions on both sides taking into account the effect of surface bond-order loss for the grains in a film. Electron scattering by film surfaces is also considered following the lines of Fuchs’ ...
