Extended Data Fig. 3: Cross-sectional TEM analysis of exfoliated STO membrane.
From: Heterogeneous integration of single-crystalline complex-oxide membranes
a, Low-magnification TEM image of STO membrane supported by the Ni stressor layer. b, Zoom-in of polycrystalline domains caused by residues left on graphene after transfer. c, High-resolution TEM image of the STO membrane (centre), with selected area electron diffraction (left) and high-resolution TEM (right) images, confirming the overall single-crystallinity of the membrane. The single-crystalline STO membrane has a cubic structure in the \(Pm\bar{3}m\) space group with lattice distances d100 and d001 of 0.4 nm.
