(a) Cut at constant qz through the NR-(111)-signal from a NR in the centre of the array. Interference fringes measure a size of 500 nm. (b) Simulated intensity distribution obtained from two-dimensional fast Fourier transform of a homogeneous hexagon (black inset). (c) Amplitude and phase of the diffracting NR obtained by phase-retrieval analysis of the data shown in (a). |
