The Langmuir-Blodgett film deposition technique has recently been used to fabricate a variety of dense electronic and nonlinear optics devices on a single crystal silicon surface. An important technological problem arises from the use of this technique: the interdiffusion of polymer and surfactant molecules between multilayers in LangmuirBlodgett films directly affects the stability of these fi...

Indium tin oxide significantly reduces interdiffusion processes during crystallization of thin-film cathodes on stainless steel substrate to enable higher performance.

Finite element method is used to obtain numerical solution to the Danielewski-Holly model of interdiffusion for non-ideal, multi-component open systems and concentration dependent diffusivities. The definition of the week solution of the initial-boundary-value problem of interdiffusion is formulated. Using the Galerkin scheme, the approximate solution to the problem has been derived. The numeri...

Interdiffusion coefficients were measured in NiSi and NiCr systems from diffusion couples under hydrostatic pressures between 50 326 MPa, at 1200 °C. Uniaxial compression creep tests also carried out on Ni–Cr 885 °C, 940 °C 1000 with stress values 0 25 to observe the effect of applied diffusion. A numerical inverse method was elaborated determine interdiffusion that takes into account plastic s...

The thermal stability of an iron/molybdenum bilayer was determined using Rutherford backscattering spectrometry and X-ray diffraction. Substantial interdiffusion (3%) was observed upon annealing at 973 K for one hour. High temperature annealing of Fe/Mo layers in oxygen ambient is therefore not suitable for the formation of magnetite layers.

The mechanical properties of the SiC/Al interface are crucial in estimating overall strength this ceramic-metal composite. present work investigates interdiffusion at using molecular dynamics simulations. One cubic and one hexagonal SiC with a higher probability orientations contact Al examined as two samples metal-matrix nanocomposites whisker particulate reinforcements. These reinforcements S...
