Similarly, Si-0 and A1-0 lattice defect luminescence in the UV-Visible spectra were observed in addition to a previously unassigned IR luminescence.
The enhancement in intensity at 345[degrees]C in calcite may be attributed to the cause of lattice defects. According to Lewis (1968), the peak at around 300[degrees]C is caused only due to lattice defect and not by any other impurity content.
The increase in the band gap was attributed to the reduction in the lattice defect [20] and the vacancies site [21].
The regular repeats (Fig 4d) show that the material is well crystallized without any lattice defect and other stacking variants.
The peaks at 350, 500 and 600[degrees]K are found in nearly all natural calcite specimens but the 600[degrees]K is probably due to lattice defect structure rather than [Ni.sup.2+] or [Co.sup.2+] .
While ordinary diamonds consist of a regular grid of carbon atoms, lattice defects have been deliberately incorporated into the diamonds in Majer's lab.
In-depth analysis using the Rietveld method of X-ray data is carried out, in terms of phase composition, crystallite size, microstrain, lattice parameter, and lattice defects such as dislocation density and stacking faults.
Section three presents several contributions addressing the tuning of relationships between morphology, interface properties, lattice defects, and charge transport.
A paper has been published to model realistically the electrical conductivity in ceramic lattices used as electrolytes for SOFCs [9]; the essential feature of the model was to introduce the interaction between charge carriers and lattice defects, in particular as concerns the presence of dislocations.
When steel undergoes plastic deformation, its internal energy increases because of the growing number lattice defects. The structure of the steel thus becomes metastable.
The final chapter discusses practical applications of the technique, such as detecting twin boundaries and lattice defects and analyzing polymers.
