Early Stage Growth of Amorphous Thin Film: Average Kinetics, Nanoscale Dynamics and Pressure Dependence
Chenyu Wang, Karl F. Ludwig, Christa Wagenbach +5
We used the Coherent Grazing Incidence Small Angle X-Ray Scattering (Co-GISAXS) technique to study the average kinetics and nanoscale dynamics during early-stage a-WSi sputter…
Co-GISAXS as a New Technique to Investigate Surface Growth Dynamics
Meliha G. Rainville, Christa Hoskin, Jeffrey G. Ulbrandt +5
Detailed quantitative measurement of surface dynamics during thin film growth is a major experimental challenge. Here X-ray Photon Correlation Spectroscopy with coherent hard X-ray…
Using coherent X-rays to directly measure the propagation velocity of defects during thin film deposition
Jeffrey G. Ulbrandt, Meliha G. Rainville, Christa Hoskin +5
The properties of artificially grown thin films are often strongly affected by the dynamic relationship between surface growth processes and subsurface structure. Coherent mixing o…
Interfacial Ionic Liquids: Connecting Static and Dynamic Structures
Ahmet Uysal, Hua Zhou, Guang Feng +8
It is well-known that room temperature ionic liquids (RTILs) often adopt a charge-separated layered structure, i.e., with alternating cation- and anion-rich layers, at electrified…
Evolution Process of Wurtzite ZnO Films on Cubic MgO (001) Substrates: a Structural, Optical and Electronic Investigation of the Misfit Structures
Hua Zhou, Hui-Qiong Wang, Yaping Li +8
The interface between hexagonal ZnO films and cubic MgO (001) substrates, fabricated through molecular beam epitaxy, are thoroughly investigated. X-ray diffraction and (scanning) t…
Understanding Controls on Interfacial Wetting at Epitaxial Graphene: Experiment and Theory
Hua Zhou, P. Ganesh, Volker Presser +8
The interaction of interfacial water with graphitic carbon at the atomic scale is studied as a function of the hydrophobicity of epitaxial graphene. High resolution X-ray reflectiv…
Growth of macroscopic-area single crystal polyacene thin films on arbitrary substrates
Randall L. Headrick, Hua Zhou, Binran Wang +7
Organic electronic materials have potential applications in a number of low-cost, large area electronic devices such as flat panel displays and inexpensive solar panels. Small mole…
Pressure-dependent transition from atoms to nanoparticles in magnetron sputtering: Effect on WSi2 film roughness and stress
Lan Zhou, Yiping Wang, Hua Zhou +6
We report on the transition between two regimes from several-atom clusters to much larger nanoparticles in Ar magnetron sputter deposition of WSi2, and the effect of nanoparticles…
Anomalous Expansion of the Copper-Apical Oxygen Distance in Superconducting LaCuO - LaSrCuO Bilayers
Hua Zhou, Yizhak Yacoby, Ron Pindak +3
We have introduced an improved X-ray phase-retrieval method with unprecedented speed of convergence and precision, and used it to determine with sub-Ångstrom resolution the complet…
Wavelength Tunability of Ion-bombardment Induced Ripples on Sapphire
Hua Zhou, Yiping Wang, Lan Zhou +6
A study of ripple formation on sapphire surfaces by 300-2000 eV Ar+ ion bombardment is presented. Surface characterization by in-situ synchrotron grazing incidence small angle x-ra…
