This paper presents a review of literature concerned with the vibration modelling of rolling element bearings that have localised and extended defects.
Strong thermal gradients in low-thermal-conductivity ceramics may drive extended defects, such as grain boundaries and voids, to migrate in preferential directions.
HRTEM studies of multilayer Ge/Si heterostructures with buried arrays of Ge huts have shown that the domains of stretched lattice occurring over Ge clusters in Si layers at high Ge coverages usually do not contain extended defects.
It has recently been shown by SSRM mapping, performed in cross-section, that extended defects in 3C-SiC cause a localized lowering of the resistance through the layer [16].
Extrinsic gettering refers to gettering that employs external means to create the damage or stress in the silicon lattice in such a way that extended defects needed for trapping impurities are formed.
In particular, for growth of non-polar m-plane GaN/AlGaN multi-QWs, extended defects introduced by the epitaxial process, such as stacking faults or dislocations, were not observed [13].
With the fluence increasing, more extended defects lead to the symmetry variation and the transformation of a possible δ-phase structure.
The contact-induced extended defects can be observed to extend radially out from the center of the indentation along < 11-20 > crystal orientation, a characteristic of the hexagonal crystal system.
The level E c —0.83 eV was not observed in the InAs/In0.15Ga0.85As samples (Fig. 6): in previous works on DLTS, such a level was attributed to extended defects related to strain relaxation in the vicinity of QDs [46].
This could be used for imaging whole nanoparticles with picometer-scale precision (as shown here) or imaging other larger structure such as surfaces, extended defects, far-reaching strain fields, and interfaces.
An enhancing effect of chemical etching on k* is found for both strain states and attributed to the removal of a surface layer that is enriched with Sr. From (ii) we get evidence that tensile strain enhances and compressive strain reduces oxygen exchange kinetics compared to films without a predominant strain state, despite the likely presence of extended defects in this system.
