  Finding viable Kagome lattices is vital for materializing novel phenomena in
quantum materials. In this work, we performed element substitutions on CsV3Sb5
with space group P6/mmm, TbMn6Sn6 with space group P6/mmm, and CsV6Sb6 with
space group R-3 m, respectively, as the parent compounds. A total of 4158
materials were obtained through element substitutions, and these materials were
then calculated via density function theory in high-throughput mode. Afterward,
48 materials were identified with high thermodynamic stability
(E_hull<5meV/atom). Furthermore, we compared the thermodynamic stability of
three different phases with the same elemental composition and predicted some
competing phases that may arise during material synthesis. Finally, by
calculating the electronic structures of these materials, we attempted to
identify patterns in the electronic structure variations as the elements
change. This work provides guidance for discovering promising AM3X5/AM6X6
Kagome materials from a vast phase space.
