Composition, Size, and Surface Functionalization dependent Optical Properties of Lead Bromide Perovskite Nanocrystals
Palvasha Ijaz, Muhammad Imran, Márcio M. Soares +6
The photoluminescence (PL), color purity, and stability of lead halide perovskite nanocrystals depend critically on the surface passivation. We present a study on the temperature d…
Temperature and high-pressure dependent X-ray absorption of SmNiO3 at the Ni K- and Sm L3- edges
Néstor E. Massa, Aline Y. Ramos, Helio C. N. Tolentino +3
We report on XANES and EXAFS measurements of SmNiO3 from 20 K to 600 K and up to 38 GPa at the Ni K- and Sm L3- edges. A multiple component pre- Ni K-edge tail is understood origin…
Strain driven monoclinic distortion of ultrathin CoO films in CoO/Pt(001) and exchange-coupled CoO/PtFe/Pt(001) systems
Anne D. Lamirand, Maurizio De Santis, Marcio M. Soares +3
The structure and strain of ultrathin CoO films grown on a Pt(001) substrate and on a ferromagnetic PtFe pseudomorphic layer on Pt(001) have been determined with insitu and real ti…
Depth dependent local structures in thin films unraveled by grazing incidence x-ray absorption spectroscopy
Narcizo M. Souza-Neto, Aline Y. Ramos, Helio C. N. Tolentino +2
A method of using X-ray absorption spectroscopy (XAS) together with resolved grazing incidence geometry for depth profiling atomic, electronic, chemical or magnetic local structure…
Stability of Jahn Teller distortion in LaMnO3 under pressure: An x-ray absorption study
Aline Y. Ramos, Hélio C. N. Tolentino, Narcizo M. Souza-Neto +3
The local environment of manganese atoms in LaMnO3 under pressure up to 15.3 GPa has been studied by x-ray absorption spectroscopy. For pressures below 8 GPa, no change is detected…
Linear and Circularly Polarized Light to Study Anisotropy and Resonant Scattering in Magnetic Thin Films
Helio C. N. Tolentino, Julio C. Cezar, Narcizo M. Souza-Neto +1
The remarkable polarization properties of the synchrotron light have lead to the advent of modern synchrotron-related spectroscopic studies with angular and/or magnetic selectivity…
