A quantitative relationship between material hardness and the defect concentration and defect diffusion coefficient has been established.
Using an instability criterion for a penny-shaped crack under shear with interfacial friction, a relationship between yield strength and the corresponding defect size is established, and the defect concentration is estimated.
The defect concentration has been determined from Raman studies.
Resistivity measurements can be used to qualitatively determine the defect concentration in a metal film.
The defect concentration in CNTs can be studied by Raman spectroscopy.
Also, the negligible defect luminescence in Figure 7b illustrates that the defect concentration in the GaN nanowires, grown with the Ga source at 20 cm, was extremely low.
However, introducing any defect (even "very symmetrical", such as N-N substitutional pair) breaks the crystal symmetry resulting in defect-induced infrared absorption, which is the most common tool to measure the defect concentrations in diamond.
We conducted a study on the relationship between the surface defect concentration and the photocatalytic activity having different modification time for the hydrogen production.
It is shown that, due to the relationship between flow defect concentration and free volume model, it is impossible to determine the equilibrium flow defect concentration.
It is also shown that, due to the relation between flow defect concentration and free volume, it is not possible to deduce the equilibrium flow defect concentration directly from mechanical measurements.
