Cspbbr3 orthorhombic phase

WebIntuitively, the cubic phase has highly symmetric Pb–Br 6 octahedral sites, so this phase has symmetric surfaces. However, the orthorhombic phase has rotated octahedral Pb–Br 6 sites which break the symmetry on surfaces. Therefore, the (110) o surface and (001) o surface are different terminations on the orthorhombic phase . WebFig. 1 show the peak deviations and phase transformations that occur upon heating with the general disappearance of the double peaks related to the distorted orthorhombic phase observed at low temperature to a single peak (with Ka 1 and Ka 2) related to the cubic phase. For instance, (002) and (101) trans-
