摘要：

High-crystallinity films of the Sr1-xCuOy infinite-layer oxide were grown by molecular beam epitaxy combined with a mass-separated low-energy oxygen ion (O+) beam as the oxygen source. The film growth was carried out under an ultralow background partial pressure of molecular oxygen, estimated to be less than 2 x 10(-11) Torr during growth. Reflection high-energy electron diffraction patterns of the films showed well-defined Kikuchi lines. Precise measurement of the rocking curves for the films resulted in sharp peaks with a full-width at half-maximum of 0.016 degrees.
