Query: Reconstruction-Stabilized Epitaxy of LaCoO3/SrTiO3(111) Heterostructures
  by Pulsed Laser Deposition   Unlike widely explored complex oxide heterostructures grown along [001], the
study of [111]-oriented heterointerfaces are very limited thus far. One of the
main challenges is to overcome the polar discontinuity that hinders the epitaxy
of atomically sharp interfaces. Here, by taking the LaCoO3/SrTiO3(111) as a
prototype, we show that the reconstruction, which effectively compensates the
surface polarity, can stabilize the epitaxy of the heterostructure with polar
discontinuity. Reconstructed substrate surface is prepared, while the growth is
controlled to form reconstruction on the film surface. To suppress the chemical
diffusion across the interface, the growth is interrupted between each unit
cell layer to allow the lattice relaxation at a lowered temperature. In this
way, high quality two-dimensional growth is realized and the heterointerfaces
exhibit sharpness at the atomic scale. Our work provides a path to precisely
control the growth of complex oxide heterostructures along polar orientations
that exhibit emergent quantum phenomena.
