Figure 3
(Colour online) Two-dimensional images of an array of square junctions [from (a) to (c), 120, 30 and 10 µm size, respectively] (top = optical image, bottom = area detector image). The images were recorded far from the focal point. The different parts of the sample are identified as follows: (1) external contacts; (2) square junctions; (3) alignment marks used in lithography; (4) parts of the film not removed during the lithography. Images were corrected by the projection due to the Bragg angle and focusing effect (sample curvature).  [article HTML]
