Abstract
We investigate the blister features that appear in small-angle hollow- cone dark-field images of overlapping layers of delaminated calcium ni obate. Modelling shows that the blister contrasts are caused by pocket s of gas or liquid that have become trapped when calcium niobate layer s are brought into contact and reseal. Hollow-cone dark-field contrast is primarily due to diffraction variations caused by sheet bending ar ound the pressurized cracks.
