Vacancies and vacancy-oxygen complexes in silicon: Positron annihilation with core electrons
(The American Physical SocietyGrupo Estado SólidoEstados Unidos, 2017)
Iron and oxygen vacancies at the hematite surface: Pristine case and with a chlorine adatom
(Royal Society of Chemistry, 2020-11)
Defect complexes play critical roles in the dynamics of water molecules in photoelectrochemical cell devices. For the specific case of hematite (α-Fe2O3), iron and oxygen vacancies are said to mediate the water splitting ...
The role of oxygen vacancies and their location in the magnetic properties of Ce1-xCuxO2-delta nanorods
(Royal Soc Chemistry, 2015-01-01)
Ceria (CeO2) is a promising dilute magnetic semiconductor. Several studies report that the intrinsic and extrinsic structural defects are responsible for room temperature ferromagnetism in undoped and transition metal doped ...
Oxygen related defects and vacancy clusters identified in sputtering grown UOx thin films by positron annihilation techniques
(Elsevier, 2021-08)
We experimentally studied the formation of vacancy clusters and oxygen related defects in uranium oxide (UOx) thin films (<70 nm) changing the stoichiometry in the x = 2.2?3.5 range. Films were deposited on Si(0 0 1) by ...
Key Role of Oxygen-Vacancy Electromigration in the Memristive Response of Ferroelectric Devices
(American Physical Society, 2020-10)
Ferroelectric memristors are intensively studied due to their potential implementation in data storage and processing devices. In this work we show that the memristive behavior of metal-ferroelectric-oxide-metal devices ...

Correlation between photoluminescence and structural defects in Ca 1+x Cu 3 - X Ti 4 O 12 systems
(2013-01-01)
Ca1+xCu3-xTi4O12 powders were synthesized by a conventional solid-state reaction. X-ray diffraction (XRD) was performed to verify the formation of cubic CaCu3Ti4O 12 (CCTO) and orthorhombic CaTiO3 (CTO) phases at long ...
