Instrument for in situ hard x-ray nanobeam characterization during epitaxial crystallization and materials transformations
Samuel D. Marks, Peiyu Quan, Rui Liu +5
Solid-phase epitaxy (SPE) and other three-dimensional epitaxial crystallization processes pose challenging structural and chemical characterization problems. The concentration of d…
Burton-Cabrera-Frank theory for surfaces with alternating step types
Guangxu Ju, Dongwei Xu, Carol Thompson +5
Burton-Cabrera-Frank (BCF) theory has proven to be a versatile framework to relate surface morphology and dynamics during crystal growth to the underlying mechanisms of adatom diff…
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…
Dynamics of Atomic Steps on GaN (0001) during Vapor Phase Epitaxy
Guangxu Ju, Dongwei Xu, Carol Thompson +5
Images of the morphology of GaN (0001) surfaces often show half-unit-cell-height steps separating a sequence of terraces having alternating large and small widths. This can be expl…
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…
High-energy coherent X-ray diffraction microscopy of polycrystal grains: first steps towards a multi-scale approach
Siddharth Maddali, Jun-Sang Park, Hemant Sharma +7
We present proof-of-concept imaging measurements of a polycrystalline material that integrate the elements of conventional high-energy X-ray diffraction microscopy with coherent di…
