Sequential deposition enables suppression of spontaneous donor enrichment of the surface in spin-coated films

JPhys Materials
Sequential deposition (SD) through independent processing of donor and acceptor materials, has emerged as a promising strategy to enable better control over the active layer morphology of organic solar cells.

Spin-resolved NEXAFS from resonant X-ray scattering (RXS)

Journal of Synchrotron Radiation, 2001
Resonantly excited metal K core line spectra of NiO, MnO, CoO and other compounds have been investigated at the beamlines X21 (NSLS/BNL), BW1 and W1.1 (HASYLAB/DESY). From analysis of spectral data we have drawn the following conclusions: -spin conservation is valid in the scattering process, for excitations below the absorption threshold as well as ...

Self-association of organic solutes in solution: a NEXAFS study of aqueous imidazole.

Faraday discussions, 2015
N K-edge near-edge X-ray absorption fine-structure (NEXAFS) spectra of imidazole in concentrated aqueous solutions have been acquired. The NEXAFS spectra of the solution species differ significantly from those of imidazole monomers in the gas phase and ...

Beagle: a near-edge X-ray absorption fine-structure spectroscopy data processing solution for beamline experiments at Pohang Accelerator Laboratory

Journal of Synchrotron Radiation
Near-edge X-ray absorption fine-structure (NEXAFS) spectroscopy is a powerful tool for identifying chemical bonding states at synchrotron radiation facilities. Advances in new materials require researchers in both academia and industry to measure tens to

Correlation of conductivity and angle integrated valence band photoemission characteristics in single crystal iron perovskites for 300 K < T < 800 K: Comparison of surface and bulk sensitive methods

, 2010
A single crystal monolith of La0.9Sr0.1FeO3 and thin pulsed laser deposited film of La0.8Sr0.2Fe0.8Ni0.2O3 were subject to angle integrated valence band photoemission spectroscopy in ultra high vacuum and conductivity experiments in ambient air at ...

NEXAFS Sensitivity to Bond Lengths in Complex Molecular Materials: A Study of Crystalline Saccharides.

Journal of Physical Chemistry B, 2015
Detailed analysis of the C K near-edge X-ray absorption fine structure (NEXAFS) spectra of a series of saccharides (fructose, xylose, glucose, galactose, maltose monohydrate, α-lactose monohydrate, anhydrous β-lactose, cellulose) indicates that the ...

Effect of co-adsorption dye on the electrode interface (Ru complex/TiO2) of dye-sensitized solar cells

AIP Advances, 2013
The co-adsorption interface structure of isothiocyanate (R-N=C=S) in N719 dye was investigated using a system of N719 alone and an N719 + D131 co-adsorption system.

NEXAFS and XPS of p-Aminobenzoic Acid Polymorphs: The Influence of Local Environment

, 2016
Nitrogen K-edge XPS and NEXAFS of the two polymorphic forms of para- aminobenzoic acid (PABA) are significantly different reflecting variation in hydrogen bonding. Alteration in hydrogen bonding at the amino group leads to a shift to high energy for both

Effect of the fluorination technique on the surface-fluorination patterning of double-walled carbon nanotubes

Beilstein Journal of Nanotechnology, 2017
Double-walled carbon nanotubes (DWCNTs) are fluorinated using (1) fluorine F2 at 200 °C, (2) gaseous BrF3 at room temperature, and (3) CF4 radio-frequency plasma functionalization.
