"Two-dimensional surface phase diagram of a multicomponent perovskite oxide: La0.8Sr0.2MnO3(110)";
Physical Review Materials, 5 (2021), S. L0924011 - L0924017.



Kurzfassung englisch:
The many surface reconstructions of (110)-oriented lanthanum strontium manganite (La0.8Sr0.2MnO3, LSMO)
were followed as a function of the oxygen chemical potential (μO) and the surface cation composition.
Decreasing μO causes Mn to migrate across the surface, enforcing phase separation into A-site-rich areas
and a variety of composition-related, structurally diverse B-site-rich reconstructions. The composition of these
phase-separated structures was quantified with scanning tunneling microscopy, and these results were used to
build a two-dimensional phase diagram of the LSMO(110) equilibrium surface structures.
