FIG. 5. Cross-sectional TEM images of a superlattice with L=7.4 nm and XV=0.5. The upper and lower panels show overview and detailed lattice resolved images, respectively.
"This 3D morphology is frozen-in in the superlattices by capping the undulated V layers with Mo, which leads to a ‘‘lasagne-like’’ structure as seen in Fig. 5."
