Angle-resolved photoemission spectroscopy of Sr1-xLaxCuO2 thin films grown by molecular-beam epitaxy
Abstract: Among the multitude of known cuprate material families and associated structures, the archetype is "infinite-layer" ACuO2, where perfectly square and flat CuO2 planes are separated by layers of alkaline earth atoms. The infinite-layer structure is free of magnetic rare earth ions, oxygen chains, orthorhombic distortions, incommensurate superstructures, ordered vacancies, and other complications that abound among the other cuprate material families. I will present in situ angle-resolved photoemission spectroscopy measurements of epitaxially-stabilized Sr1-xLaxCuO2 thin films grown by molecular-beam epitaxy. By studying a completely different electron-doped cuprate, we can for the first time independently confirm that the cuprate phase diagram is fundamentally asymmetric and provide a coherent framework for understanding the generic properties of all electron-doped cuprates.
