WebGISAXS/GIWAXS data and photoluminescence (PL) spectra with in situ heating show that the MAPI nanocrystals change from tetragonal-to-cubic crystal structure at 55−60 °C and begin to degrade at temperatures as low as 75 °C to PbI 2. Upon reaching temperatures as high as 150 °C, the PbI 2 byproduct exhibits both hexagonal and rhombohedral ...

WebGISXAS data could be interpreted the same way as small angle x-ray scattering (SAXS) experiment. Instead of having transmission geometry as SAXS, GISAXS relied on reflection of x-ray from the samples, which enables the thin film characterization, as more sample volume could be probed. The typical experiment setup is shown in figure 1 [4] .
