Fig. 1: Synthesis of the lateral oxide homostructures.
From: Twisted oxide lateral homostructures with conjunction tunability
a Process flow for fabricating twisted lateral oxide homostructures. (i) Growth of STO with a LSMO sacrificial layer on (110)-oriented STO single crystal substrate. (ii) Etching of the LSMO sacrificial layer. (iii) Releasing and (iv) transferring the freestanding STO layer with designated twist angle with respect to the selected single-crystal carrier substrates. (v) Deposition of BFO thin film on the twisted template. b Topography images of (110)-oriented BFO grown on pristine STO, boundary, and FS-STO region, respectively. The [001]pc-oriented stripes serve as the direction reference of epitaxial BFO, identifying the in-plane directions of (110)-oriented BFO and the twist angle (denoted as angle φ) at the boundary of pristine STO and FS-STO region.
