Technical and economic considerations have identified an opportunity for composite materials which combine certain advantageous features of both noble and base metals. During an investigation of some platinum cladding techniques and of the properties of the resulting bimetals, data have been amassed which could have relevance to industrial a s well as to decorative applications. Here the effect...

The study has established that reactor radiation leads to a significant increase of interdiffusion coefficients in Mo - W alloy compared thermally activated diffusion at temperatures ~1500°С. Furthermore, weakening their concentration dependence is observed. approximation procedure developed this work allowed approximating experimental data for each sample using variation only one parameter. It...

We report results of high-resolution sputter depth profiling of an alternating MgO/ZnO nanolayer stack grown by atomic layer deposition (ALD) of ≈5.5 nm per layer. We used an improved dual beam time-of-flight secondary ion mass spectrometer to measure (24)Mg(+) and (64)Zn(+) intensities as a function of sample depth. Analysis of depth profiles by the mixing-roughness-information model yields a ...

Pollycrystalline-Si/GaAs interfaces have been prepared by depositing hydrogenated amorphous Si (a-Si:H) onto GaAs in a silane plasma at 450°C and annealing at temperatures between 600 and 1020 dc. Rutherford backscattering, secondary ion mass spectroscopy, and transmission electron microscopy show that the resulting polycrystaHine-SilGaAs interface is metaBurgically stable when the Si is und.op...
