Figure 4
Images of a step aligned approximately along the scattering plane with the sample (a) on specular and (b) tilted by δχ = 1° (in a direction transverse to the scattering plane). (c) Intensity line scans corresponding to the white box positions in (a) and (b), for δχ = 0 (red triangles) and (b) δχ = −1 (blue squares, offset vertically by 0.1). The condenser lens focus is on the sample position as in images in Figs. 2(g) and 2(h). (d) Schematic of the sample tilt direction used for the image in (b). |
