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…
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…
Spontaneous Repairing Liquid Metal/Si Nanocomposite as a Smart Conductive-Additive-Free Anode for Lithium-ion Battery
Bing Han, Yu Yang, Xiaobo Shi +7
Silicon is a promising candidate for negative electrodes due to its high theoretical specific capacity (~3579 mAh g-1) and low lithiation potential (~0.40 V vs Li). However, its pr…
Stacking and electric field effects on the electronic properties of the layered GaN
Dongwei Xu, Haiying He, Ravindra Pandey +1
Stability and electronic properties of atomic layers of GaN are investigated in the framework of the van der Waals-density functional theory. We find that the ground state of the l…
