Abstract

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