Electronic Excitations of Hematite Heteroepitaxial Films Measured by Resonant Inelastic X-Ray Scattering at the Fe L-edge
David S. Ellis, Ru-Pan Wang, Deniz Wong +9
Resonant Inelastic X-Ray Scattering (RIXS) spectra of hematite were measured at the Fe L3-edge for heteroepitaxial thin films which were undoped and doped with 1% Ti, Sn or Zn, in…
The rust challenge -- On the correlations between electronic structure, excited state dynamics and photoelectrochemical performance of hematite photoanodes for solar water splitting
Daniel A. Grave, Natav Yatom, David S. Ellis +2
In recent years, hematite potential as a photoanode material for solar hydrogen production has ignited a renewed interest in its physical and interfacial properties, which continue…
The spatial collection efficiency of photogenerated charge carriers in photovoltaic and photoelectrochemical devices
Gideon Segev, Hen Dotan, David S. Ellis +7
The spatial collection efficiency portrays the driving forces and loss mechanisms in photovoltaic and photoelectrochemical devices. It is defined as the fraction of photogenerated…
Wavelength Dependent Photocurrent of Hematite Photoanodes: Reassessing the Hole Collection Length
Asaf Kay, Daniel A Grave, Kirtiman D Malviya +3
The photoelectrochemical behavior of a planar 1 cm2 thick Ti-doped hematite film deposited on F:SnO2 coated glass was studied with both front and back illumination. Despite low qua…
Bulk-sensitive Imaging of Twin Domains in LaSrCuO under Uniaxial Pressure
Xin Yu Zheng, Renfei Feng, D. S. Ellis +1
We report our study of twin domains in under uniaxial pressure. Using bulk-sensitive x-ray microdiffraction in Laue geometry, we image the distribution of twin…
Magnetic states at the surface of alpha-Fe2O3 thin films doped with Ti, Zn or Sn
David S. Ellis, Eugen Weschke, Asaf Kay +6
The spin states at the surface of epitaxial thin films of hematite, both undoped and doped with 1% Ti, Sn or Zn, respectively, were probed with x-ray magnetic linear dichroism (XML…
