Diffusion profiles of the zinc isotopes due to the annealing were evaluated using secondary ion mass spectrometry SIMS. Guerrero and H. Authors: Boris A. Often diffusion measurements have to be performed in samples for which initial experimental conditions do not offer the possibility of using conventional diffusion analytical solutions. Authors: A. The use of simulations in order to model physical phenomena is quite common nowadays, and highly complex models have been developed. Defect and Diffusion Forum Volumes The simulation fits the SIMS profiles and shows that the SiO diffusion is greatly retarded by the oxidation with O2 from the oxygen-containing atmosphere and that the O self-diffusion therefore becomes distance-dependent.

Tsuchiya and K. Fukatsu, T. The thin films were annealed at various diffusion annealing temperatures. Furthermore, the simpler the model small number of parameters used in the simulation, the more relevant the measurement minimum error.

However, simulations can be of use in these cases.

The 18O isotope concentration has been measured by the acceleration nuclear microanalysis method. Gosset, J.

Gunji, M. They are time consuming compared to the use of analytical solutions, but are more flexible regarding initial conditions and problem complexity.

However, two types of simulations have to be considered: i simulations aiming to understand and predict phenomena, and ii simulations for measurement purposes, aiming to extract the average value of a physical parameter from experimental data.
