Figure 6: LCO thin film static electron diffraction. Multiple diffraction orders of sharp Bragg spots can be seen indicating a transmission-like pattern. These patterns come from transmission through the three-dimensional islands observed in AFM measurements. The patterns are indexed based on the tetragonal structure of LCO. (a) The electron beam is incident 4 to in-plane Cu–O bond direction (nodal direction); whereas in (b) the beam is incident along the Cu–O bond direction (antinodal direction). The angle of incidence was around 1. in both cases.
