From: Signatures of enhanced out-of-plane polarization in asymmetric BaTiO3 superlattices integrated on silicon

Fig. 2

a XRD θ-2θ scans of the SLs with varied layer thickness of BTO grown on Si/STO. The arrows indicate the (001) and (002) main peaks. The satellite peaks are indexed for the L8B12S5 SL. b RSMs around the (103)pc reflection of L8B0S5, L8B2S5 and L8B4S5. c Extracted in-plane (mean out-of-plane) lattice constant, a (cm) as a function of the layer number of BTO. The dashed lines indicate the lattice constants of bulk STO, LMO and BTO.
