Figure 7
A simulated 2D scattering pattern from a layer of graphene (containing 25 × 25 unit cells; partly shown in the inset) aligned parallel to the xz plane (where the beam is along the y axis). The high intensity around q = 0 has been blacked out to emphasize the correlation peaks at higher q values. To make the different peaks more prominent, the intensities were rescaled using scikit's (van der Walt et al., 2014) rescale_intensity function. The simulated peaks fall on the peaks expected from the reciprocal lattice of graphene [equation (22)]. |
