(a) Schematic illustrating the transmission X-ray scattering geometry used in the present study. (b) A limiting case in which the meniscus-inducing Si substrate is normal to the incident X-ray beam ( = 0). (c) A limiting case in which the X-ray-illuminated surface is vertical ( = 0). In (a)–(c), the coordinates represent the laboratory frame, with the axis along the gravity axis and the axis along the horizontal incident X-ray beam. The coordinates (x,y,z) are defined with respect to the local surface at the X-ray-illuminated spot, with the z axis along the surface normal. |
