In science:

It could be due to the positron trapping rate balance between different vacancy traps shifting the S and W values to the annihilation characteristics of the NV− vacancy defect which has a high trapping coefficient, without excluding that annealing can partially remove the complex vacancies.

We showed that the conversion efficiency of nitrogen into NV− increases with the irradiation fluence, up to a point where further increase leads to a reduction in this conversion rate, most likely due to the creation of complex vacancies stable under 800◦/20 h annealing.

In particular, the relatively low values of derivatives D3 for the pre-coarsening stage can be related to the strong vacancy trapping for this stage (illustrated by Fig. 6a in ) which should result in a sharp increase of the effective rate γ ef f CuFe in Eq. (8) .

N [1 − (2 + uD )mi ] . i = mi (1 − mi−1) In the bulk of the system, the hopping rates for say a positive particle do not distinguish between a negative particle and a vacancy.
Spontaneous Symmetry Breaking in a Non-Conserving Two-Species Driven Model
In the limit β → 0, Ω → 0 the only relevant configurations are those composed of three blocks, containing (from left to right) negative particles, vacancies, and positive particles. A configuration of this type is long-lived, as all exit rates from it scale to zero.
Spontaneous Symmetry Breaking in a Non-Conserving Two-Species Driven Model
First, a particle can leave the system through a boundary with rate β , leaving a vacancy behind it.
Spontaneous Symmetry Breaking in a Non-Conserving Two-Species Driven Model
This vacancy can travel into the system with rate (1 + α)−1 , in which case the system is again in a three-block configuration.
Spontaneous Symmetry Breaking in a Non-Conserving Two-Species Driven Model
First, a particle can be attached to the system in the vacancy domain with rate ωA(N − x − y ).
Spontaneous Symmetry Breaking in a Non-Conserving Two-Species Driven Model
Second, a positive (negative) particle can be detached from the system with rate ωD x (ωD y ), thus creating a vacancy within a particle block.
Spontaneous Symmetry Breaking in a Non-Conserving Two-Species Driven Model
As already noticed, rates (4) reformulated in terms of vacancies correspond to the rule that a vacancy can move only if the initial and final sites have at least s neighboring vacancies, where s = 1 in the case we are considering.
Dynamical arrest, tracer diffusion and Kinetically Constrained Lattice Gases
So we consider the chain as an open system for vacancies, which hop with the rates derived from the motion of the original beads.

Moreover, if such a system is driven by a field, the transition rates not only depend on the vacancy distribution, but also on the direction of the connecting links.
Exact Solution for a 1-dimensional model for Reptation
Lattice gases in the RT model can be considered, in the limit of concentration c → 1, as models with a low concentration of vacancies in random lattices, whose transition rates into the sites are specified.
