From: New three-dimensional flat band candidate materials Pb2As2O7 and Pb2Sn2O7
DOS of Pb\(_2\)As\(_2\)O\(_7\) with (a) pyrochlore structure and (b) K\(_2\)Cr\(_2\)O\(_7\)-type triclinic structure. Note that in (b), there are 22 different crystallographic sites, so the total contributions of 4 Pb sites, 4 As sites, and 14 O sites are shown.
