Thin-source concentration dependent diffusion
The diffusion of (Ca ) in NaCl has been measured for various diffusion ,times and for the temperature range (575°C-775°C), using a thin45 source of Ca tracer, rectangular geometry, and serial sectioning. The l6 2 pre-diffusion surface concentration was approximately 3xlO(Ca)-atoms!cm, which, for an …

Optimization of the Process for Semiconductor Device Fabrication in the MicrON 636 Whittemore Cleanroom Facility
… are examined qualitatively. Phosphorus diffusion in single-crystal silicon has a complex diffusion mechanism involving charged-vacancies, with concentration-dependent diffusion coefficients. It is therefore a complex mathematical problem to model the diffusion of phosphorus from a solid …

Spectroscopic Characterization of Molecular Interdiffusion at a Poly(Vinyl Pyrrolidone) / Vinyl Ester Interface
… the matrix and the fiber. The extent of mutual diffusion at the (sizing material / polymer matrix) interphase plays a critical role in determining the mechanical properties of the composite. In this research, the molecular interdiffusion across a poly(vinyl pyrrolidone))/vinyl ester monomer …
