The phrase "amount of defect" is correct and usable in written English.
It can be used in contexts related to quality control, manufacturing, or any situation where the quantity or extent of a defect is being measured or discussed.
Example: "The amount of defect in the production line has increased, prompting a review of our quality assurance processes."
Alternatives: "level of defect" or "degree of defect".
A higher crystallinity is usually believed to be beneficial for photocatalysis because of the amount of defect sites in the structure (which usually act as recombination centers).
Also, the increase in average crystal size after annealing might be due to decrease in grain boundaries and the amount of defect in the films.
Moreover, the visible-light-driven photocatalytic activity not only depend on the light absorption ability, but also affected by the amount of defect states significantly.
The concentrated H2SO4/HNO3 mixture created the maximum number of carboxylic acid groups and the highest amount of defect sites, but had very low yield (∼12%).
Furthermore, the amount of defect areas significantly reduces by using a wide course, which has the effect of both increasing the deviation from the designed fiber path and reducing the number of manufacturable designs.
Moreover, high performance of MOFs in various catalytic reactions can be correlated to the higher amount of defect structures because defects can possibly exhibit acid and/or basic properties.
Indeed, large amount of defect-related gap states generally exists in non-stoichiometric silicon nitride layers obtained by CVD process.
The Co3O4 nanowires, which possessed a length ranging from 3 to 8 μm with the aspect ratio more than 15, exhibited a reversible lithium storage capacity up to ~ 790 mAh/g when using a small amount of defect-free graphene flakes as conductive additives.
The Raman spectra show a week D band that confirms the small amount of defects.
The doping of N and S provide the graphene networks with a large amount of defects.
Only two new parameters need to be determined, they describe the size and amount of defects.
