Figure 8. Short-range fit (r range = 1-10 Å) by using (A) the tetragonal MAPbBr3 perovskite structure (I4/mcm) and (B) the orthorhombic MAPbBr3 perovskite structure (Pnma). For the PDF fit (with PDFgui 1.0), the data from Bird et al.[17] at 200 K was used together with the fixed refinement results at 200 K from Bernasconi et al.[16]. In the PDF fit, only the scale and Uiso were refined.
