Design of Oxygen Vacancy Configuration for Memristive Systems
ACS Nano, 2017Oxide-based valence-change memristors are promising nonvolatile memories for future electronics that operate on valence-change reactions to modulate their electrical resistance. The memristance is associated with the movement of oxygen ionic carriers through oxygen vacancies at high electric field strength via structural defect modifications that are ...

Ferroic nanoclusters in relaxors: the effect of oxygen vacancies
Journal of Physics: Condensed Matter, 2007Single crystals of PbSc(0.5)Ta(0.5)O(3) with suppressed and enhanced oxygen deficiencies and different degrees of long-range B-site ordering were studied by Raman spectroscopy in order to clarify the significance of the different factors for the formation and growth of ferroic clusters in relaxors.

The oxygen vacancy in Ga2O3: a double resonance investigation
Magnetic Resonance in Chemistry, 2005When produced under reducing conditions, beta-Ga2O3 is transformed into an n-type semiconductor with delocalized conduction electrons that exhibit a very strong electron spin resonance (ESR) and a strong hyperfine coupling to the gallium nuclei of the host lattice. We apply the Overhauser-shift technique to investigate single crystals of this compound.
