CsPbI3 and CH3NHPbI3 are perovskite structure with different bandgap. Those materials have been deposited on a substrate to form an alternating sandwich lamela structure. Each slab is 15nm thick. The number of slabs is 8. We consider running XRD experiment to realize how parallel are the layers.
Obtaining a broad peak at a low 2teta of 0.01deg will indicate on very good parallelism. Can you please comment on this approach Please note those perovskites are highly sensitive to high energy radiations. Thank you from advance Shay
