Abstract

Superlattices in the Pb-Tl-O system were electrodeposited at room temperature from aqueous solution. The deposition solution was 0.005 M Tl(I) and 0.100 M Pb(II) in 5 M NaOH. The superlattices grew epitaxially on oriented prelayers with either a [100] or [210] texture The out-of-plane texture of the prelayer was maintained throughout the growth of the superlattice. X-ray diffraction (XRD) showed the films to be superlattices by the presence of satellites around the main Bragg reflections. There was good agreement between XRD and scanning tunneling microscopy for the measurement of modulation wavelengths from 3 to 150 nm. Partial relaxation of coherency was observed for modulation wavelengths exceeding about 20 nm.
