X-ray reflectivity with a twist: quantitative time-resolved X-ray reflectivity using monochromatic synchrotron radiation
Howie Joress, Shane Quinlan Arlington, Timothy P. Weihs +2
We have developed an improved method of time-resolved x-ray reflectivity (XRR) using monochromatic synchrotron radiation. Our method utilizes a polycapillary x-ray optic to create…
Quick X-ray Reflectivity using Monochromatic Synchrotron Radiation for Time-Resolved Applications
H. Joress, J. D. Brock, A. R. Woll
We describe and demonstrate a new technique for parallel collection of x-ray reflectivity data, compatible with monochromatic synchrotron radiation and flat substrates, and apply i…
MBE growth of 2H-MoTe2 and 1T'-MoTe2 on 3D substrates
Suresh Vishwanath, Aditya Sundar, Xinyu Liu +17
MoTe2 is the least explored material in the Molybdenum-chalcogen family, which crystallizes in thermodynamically stable semiconducting 2H phase at \textless 500 C and 1T' metallic…
Germanium Collimating micro-Channel Arrays For High Resolution, High Energy Confocal X-ray Fluorescence Microscopy
David N Agyeman-Budu, Sanjukta Choudhury, Ian Coulthard +3
Confocal x-ray fluorescence microscopy (CXRF) allows direct detection of x-ray fluorescence from a micron-scale 3D volume of an extended, unthinned sample. We have previously demon…
Epitaxial growth of BiPtO pyrochlore
Araceli Gutierrez-Llorente, Howie Joress, Arthur Woll +5
Certain pyrochlore oxides are among the best oxygen catalysts in alkaline media. Hence, exploring epitaxial films of these materials is of great fundamental and technological inter…
Complex oxide growth using simultaneous in situ RHEED and x-ray reflectivity: When is one layer complete?
M. C. Sullivan, M. J. Ward, Araceli Gutierrez-Llorente +4
During layer-by-layer homoepitaxial growth, both the Reflection High-Energy Electron Diffraction (RHEED) intensity and the x-ray reflection intensity will oscillate, and each compl…
Spatially, Temporally and Polarization-Resolved Photoluminescence Exploration of Excitons in Crystalline Phthalocyanine Thin Films
Naveen Rawat, Zhenwen Pan, Lane W. Manning +6
The lack of long range order in organic semiconductor thin films prevents the unveiling of the complete nature of excitons in optical experiments, because the diffraction limited b…
Quantitative modeling of \textit{in situ} x-ray reflectivity during organic molecule thin film growth
Arthur R. Woll, Tushar V. Desai, James R. Engstrom
Synchrotron-based x-ray reflectivity is increasingly employed as an \textit{in situ} probe of surface morphology during thin film growth, but complete interpretation of the results…
Thickness dependence of surface diffusion in epitaxial LaAlO3 on SrTiO3(001)
J. D. Ferguson, Y. Kim, A. R. Woll +1
The LaAlO3/SrTiO3 (001) thin film materials system was studied using in situ, simultaneous x-ray diffuse scattering and specular reflectivity during pulsed laser deposition. Using…
Measurements of Surface Diffusivity and Coarsening During Pulsed Laser Deposition
J. D. Ferguson, G. Arikan, D. S. Dale +2
Pulsed Laser Deposition (PLD) of homoepitaxial SrTiO3 <001> was studied with in-situ x-ray specular reflectivity and surface diffuse x-ray scattering. Unlike prior reflectivity-bas…
Multiple Time Scales in Diffraction Measurements of Diffusive Surface Relaxation
Aaron Fleet, Darren Dale, A. R. Woll +2
We grew SrTiO3 on SrTiO3 (001) by pulsed laser deposition, using x-ray scattering to monitor the growth in real time. The time-resolved small angle scattering exhibits a well-defin…
