lamellar crystal

https://doi.org/10.1351/goldbook.L03446
A type of crystal with a large extension in two dimensions and a uniform thickness. A lamellar crystal is usually of a thickness in the $$5-50\ \text{nm}$$ range, and it may be found individually or in aggregates. The parallel chain stems intersect the lamellar plane at an @A00346@ between $$45^{\,\unicode{x26ac}}$$ and $$90^{\,\unicode{x26ac}}$$. The lamellae often have pyramidal shape owing to differences in the fold domains; as a result, one can deduce different fold planes and fold surfaces from the lamellar @MT07285@.
