The schematic diagram of the experimental setup at the 2ID-D; the inset of knife edge scan profile shows that the beam size is ∼250 nm.
Two-dimensional x-ray fluorescence mapping of Se K-line of the sample in the diamond anvil cell: 60 × 100 μm2 two-dimensional mapping with the step size is 1 μm (a), 10 × 15 μm2 two-dimensional mapping of the rectangle in Fig. 2(a) with a smaller step size of 500 nm (b). X-ray fluorescence intensity along the lines marked in Figs. 2(b) and 2(c).
An XRD pattern taken at the location marked by the arrow in Fig. 2(b) at ambient pressure in a diamond anvil cell (a), and the integrated XRD spectrum (b). The exposing time for the diffraction pattern is 180 s. The schematic diagram of the single crystal diffraction of a single nanobelt (c).
XRD patterns for the same nanobelt collected at different rotation angles.
XRD patterns taken at the same location in Fig. 3(a) at different pressures (a) and the d-spacing as the function of pressure (b).
