Therefore, we conducted calculations on each configuration of defected hexagonal lattice of h-BN when the number of vacancy is odd (mono- and tri-vacancy).
The proposed device consists of 2D square-lattice PC structures, and it is based on two PC waveguides with different symmetric guiding modes, where various configurations of defects, including elliptic or/and semi-circular defects have been incorporated.
When applied at sub-angstrom length scales the phase field crystal (PFC) model is able to describe thermally averaged atomic configurations of defects and defect processes on diffusional timescales.
The symmetry-conforming Landau theory has been developed for the description of interplay between the symmetry of the deformable crystal lattice and the configuration of crystallographic defects in martensitic alloys.
This paper investigates different tensile fracture initiation criteria on the plane-strain configuration of a defect-free openhole wellbore.
Such interaction behaves like incorporation of impurity atoms in the structure of these centers as well as the formation of complexes "dislocation-impurity" in which the mutual configuration of the defect determines the energy of optical transitions.
The total energy does not only depend on the mean value of the relative displacement, but also on the complexity of the configurations of the defects, and we draw a directed graph which shows the possible paths of the configuration change of the defects.
The equilibrium configurations are obtained using the conjugate-gradient method, and the saddle point on the minimum-energy path between two equilibrium configurations for evolution of defects, such as the nucleation/annihilation and movement of defects, is estimated using the nudged elastic-band method.
Moreover, the character and configuration of the interfacial defects is consistent with this occurring in a diffusive-displacive manner with short-range fluxes across the risers of mobile perfect interfacial disconnections.
Secondly, the effect of defects configuration on the effective thermal conductivity has been discussed systematically based on the strict mathematical calculation combined with finite element simulation.
