Fig. 1: Fabrication of LMO/BTO/STO SLs on Si/STO.

a HAADF-STEM image of the L₈B₆S₅ SL grown on Si/STO. The sketch on the left shows the ideal atomic structure in one period. The EELS elemental maps taken from the yellow rectangular area are shown in (b). c, d Show the RHEED image taken along the Si[110] azimuth and AFM image of the L₈B₆S₅ SL.
