Abstract
We know that SAD, while giving us useful information about the specimen, has two severe limitations:
-
We have to be very cautious in interpreting SAD patterns from areas which are less than ~0.5 lam in diameter. This size is large compared to the dimensions of many crystalline features that interest us in materials science (Chapter 16).
-
SAD patterns contain only rather imprecise two-dimensional crystallographic information because the Bragg conditions are relaxed for a thin specimen and small grains within the specimen (Chapter 17).
