“…To conduct our survey we decided to start from the highly symmetrical Pm3m (n 221) reference phase, 52 observed in the high temperature phase of numerous hybrid perovskites. [54][55][56][57] From this point we follow different phase transitions ( Figure 2). A key point in the observation of a SOC induced spin splitting is the loss of inversion symmetry.…”

“…Since ARPES is a surface-sensitive technique, the reduced symmetry at the surface may enhance non-centrosymmetric fields and the measured Rashba splitting. In the bulk, CH 3 NH 3 PbBr 3 forms an ordered orthorhombic structure of P nma symmetry at low temperature [41,42], and a disordered cubic structure with an average P m3m symmetry at room temperature [29,36,43]. Both structures are centrosymmetric after averaging over a length scale probed by x-ray and neutron diffraction, with no Rashba-type spin-splitting expected.…”
