Extended Data Fig. 7: Charge density mapping of conduction (CB) and valence band (VB) in the Ge perovskite.
From: Homomeric chains of intermolecular bonds scaffold octahedral germanium perovskites
using: a, F-PMA; b, Cl-PMA; c, I-PMA as cations. Note that for both cases, the contribution of the density of state on the organic parts is negligible, and thus organic molecules are not shown in the figure. Dark grey and red sphere represent the Ge and I atoms, respectively. Green and yellow colours are used for representation of positive and negative isosurfaces.
