Pressure-induced transformation of the tetragonal ArMAPbI3 phase. (a) Position of the I–Ar–MA–Ar– group within the (Pb,I)-framework. (b) Deformation of the group configuration and its connection to I atoms. Pink-coloured segments indicate the occupancies of the Ar sites. The MA–Ar and Ar–I interatomic distances are given in Å. |
