Crystal Truncation Rods from Miscut Surfaces with Alternating Terminations
Guangxu Ju, Dongwei Xu, Carol Thompson +5
Miscut surfaces of layered crystals can exhibit a stair-like sequence of terraces having periodic variation in their atomic structure. For hexagonal close-packed and related crysta…
In Situ Microbeam Surface X-ray Scattering Reveals Alternating Step Kinetics During Crystal Growth
Guangxu Ju, Dongwei Xu, Carol Thompson +5
The stacking sequence of hexagonal close-packed and related crystals typically results in steps on vicinal {0001} surfaces that have alternating A and B structures with different g…
Persistence of Island Arrangements During Layer-by-Layer Growth Revealed Using Coherent X-rays
Guangxu Ju, Dongwei Xu, Matthew J. Highland +7
Understanding surface dynamics during epitaxial film growth is key to growing high quality materials with controllable properties. X-ray photon correlation spectroscopy (XPCS) usin…
Chrono CDI: Coherent diffractive imaging of time-evolving samples
A. Ulvestad, A. Tripathi, S. O. Hruszkewycz +4
Bragg coherent x-ray diffractive imaging is a powerful technique for investigating dynamic nanoscale processes in nanoparticles immersed in reactive, realistic environments. Its te…
