Lead nitrate complexed with EDTA and lead perchlorate and sodium sulphide have been used for PbS ECALE-deposition.158159 The films were cubic and highly (200) oriented, and AFM images showed the same cubic structure.158159 PbSe films were also cubic, and the band gap of a film after 50 deposition cycles was 8000cm-1.160 PbSe/PbTe superlattices, with 4.2-nm and 7.0-nm periods, have been grown by ECALE.161 The (111) reflection in the XRD pattern showed a first-order satellite peak and one second-order peak, indicating the formation of the superlattice. AFM images of the superlattice structure showed a small amount of three-dimensional growth.161...

Figure 15.28 TEM images of (a) Au nanoparticle arrays in mesoporous silica film (b) superlattice of extracted Au nanoparticles stabilized with 1-dodecanethiol.

Fig. 13.7. GaSb-InAs superlattice (a) AFM (b) UFM with periodicity of 40 nm (arrow i) and 8nm (arrow ii). The topographical image shows that the surface is very flat (RMS roughness < 0.2 nm over 1 pm2 area). Wider layers (arrow i) are barely visible whereas the finer ones (arrow ii) are not visible at all. The very fine superlattice (arrow ii) of layers only 4 nm wide is observable in the UFM image (Dinelli er a/.

In case (iii), a blend with /PSJ = 1 -/PS-2 = 0.8 and 6 — 1.2 was examined (Koizumi el al. 1994c). For this asymmetric blend macrophase separation precedes microphase separation. A TEM image from a 30 70 blend is shown in Fig. 6.29. The continuous macrodomains consist of PI spheres in a matrix of PS, whereas the isolated domains contain PS cylinders dispersed in a matrix of PI. This was termed a superlattice structure, since two types of microphase-separated lattices coexist.

Au reconstruction is lifted and alkanethiols adopt commensurate crystalline lattice characteriized by a c(4 x 2) superlattice of a (a/3 x V3)R30°. (c) Model of commensuration condition between alkanethiol monolayer (large circles) and bulk-terminated Au surface (small circles). Diagonal slash in large circles represents azimuthal orientation of plane defined by all-trans hydrocarbon chain. (Reprint with permission from Ref.25 G. E. Poirier, Chem. Rev., 97, 1117-1127 (1997).
