Fig. 6: The convex hull of the formation energy by the DFT calculations for pseudo-binary-oxide systems containing candidate CRCs.
From: Recommender system for discovery of inorganic compounds

Closed circles (green) denote compounds on the convex hull. Closed triangles (blue) and squares (violet) denote CRCs registered in ICSD and ICDD-PDF + SpMat, respectively. Candidate compositions are given with recommendation scores in parentheses. Adopted from ref. 14 with modifications.
