Crystal orientation index
WebUnlike single crystal X-ray diffraction (X-ray Crystallography) technique, the sample will distribute evenly at every possible orientation and powder XRD collects one-dimensional information, which is a diagram of diffracted beam intensity vs. Bragg angle θ, rather than three-dimensional information.

WebApr 9, 2024 · The orientation and direction of a surface or a crystal plane may be defined by considering how the crystal plane intersects the main crystallographic axes of the solid. The use of a set of rules leads to the assignment of the Miller Indices (hkl) a set of integers that quantify the intercepts and thus may be used to uniquely identify the plane ... WebMar 23, 2024 · The discrepancy between the high and low index samples indicates that the etching process is more effective for the high index sample, implying selective etching depending on the crystal orientation. The selective etching is further supported by the lifetime of the high-frequency arc (Tau_HF, Fig. S18b, ESI † ) as well as the performance ...
