Fabrication and structural characterizations of the Ti2O3 polymorphs. a Schematic of the PLD chamber where Ti2O3 polymorphs were fabricated using the same (α-Ti2O3) target. b Unit cells for γ-Ti2O3, o-Ti2O3, and α-Ti2O3 polymorphs from top to bottom, respectively. c–e In-plane epitaxial relationships for γ-Ti2O3 on STO, o-Ti2O3, and α-Ti2O3 on Al2O3, respectively. TiO2–STO (001) view refers to view the TiO2-terminated STO (Supplementary Fig. 5) from the < 001 > direction. f HR-XRD patterns of Ti2O3 polymorphs epitaxially stabilized on the single-crystal substrates.
