Diffusional broadening
WebJan 9, 2024 · The diffusional broadening of B was analyzed by means of secondary ion mass spectrometry (SIMS) and numerically described to determine the diffusion coefficient. Additional SIMS analyses revealed a gradient in the oxygen (O) background concentration of the epitaxially doped Ge structure. A high O content observed in near-surface regions ...

As a result of small channel sizes and dimensions, microfluidic systems are almost always characterized by laminar flow due their exceedingly low … WebDec 27, 2001 · Directional transport of the electrogenerated nitrobenzene radical anion over macroscopic distances within the flow tubes, with minimal diffusional broadening, is demonstrated using an ...
WebThe diffusional broadening of the spectrum is governed by the effective jump frequency of the substitutional Mössbauer atoms which is essentially given by the product of the vacancy concentration and the vacancy-Mössbauer atom exchange jump rate whereas the fluctuation rates of the hyperfine interaction is directly given by the vacancy jump ... WebJan 28, 2024 · Radiation-enhanced diffusional broadening of implanted Ni ions (at 400-550 °C) in Fe and Fe-Cr was up to 250 nm toward the surface, which leads to a much broader near-peak-damage region where cavity swelling is suppressed. Diffusional broadening of implanted ions is calculated to be similarly pronounced for self-ion …
