Query: An efficient and reliable growth method for epitaxial complex oxide
  films by molecular beam epitaxy   Transition metal oxide heterostructures and interfaces host a variety of
exciting quantum phases and can be grown with atomic-scale precision by
utilising the intensity oscillations of $in$ $situ$ reflection high-energy
electron diffraction (RHEED). However, establishing a stable oscillation
pattern in the growth calibration of complex oxides films is very challenging
and time consuming. Here, we develop a substantially more efficient and
reliable growth calibration method for complex oxide films using molecular beam
epitaxy.
