Roughening of interfaces implies the divergence interface width $w$ with system size $L$. For two-dimensional systems $w^2$ is linear in In framework a detailed capillary wave approximation and statistical field theory we derive an expression for asymptotic behaviour $w^2$, which differs from results literature. It confirmed by Monte Carlo simulations.

CrN layers, 57 and 230 nm thick, were grown on MgO 001 at Ts=600–800 °C by ultrahigh-vacuum magnetron sputter deposition in pure N2 discharges from an oblique deposition angle =80°. Layers grown at 600 °C nucleate as single crystals with a cube-on-cube epitaxial relationship with the substrate. However, rough surfaces with cauliflower-type morphologies cause the nucleation of misoriented CrN gr...

PURPOSE One of the current challenges for the medical device industry is how to manufacture and assemble biomedical implants consisting of a metallic wire component and a fluorocarbon film without the use of an adhesive. In an attempt to answer this question, samples of Nitinol wire and fluorinated ethylene-propylene (FEP) film were surface modified by various treatments before being thermally ...

We derive a new general jump condition on a broken Weierstrass-Erdmann extremal of a vectorial variational problem. Such extremals, containing surfaces of gradient discontinuity, are ubiquitous in shape optimization and in the theory of elastic phase transformations. The new condition, which does not have a one dimensional analog, reflects the stationarity of the singular surface with respect t...
