Figure S1. Total and partial density of states calculated for HLN (P4/m) at PBE0-D level.
The Fermi level is set at 0 eV.
Figure S2. Total and partial density of states calculated for LiLN (I4/mmm) at PBE0-D level.
The Fermi level is set at 0 eV.
Figure S3. Total and partial density of states calculated for NaLN (I4/mmm) at PBE0-D level.
The Fermi level is set at 0 eV.
Table S1. Mulliken charges computed at PBE0-D for the atoms belonging to the unit cell. An
average value is reported for the 4 equatorial oxygen atoms (Oeq) and for the 2 oxygen atoms
in apical position facing out the interlayer cation (OapM)
