Charge storage in oxygen deficient phases of TiO2: defect Physics without defects
(Nature Publishing Group, 2016-07-01)
Defects in semiconductors can exhibit multiple charge states, which can be used for charge storage applications. Here we consider such charge storage in a series of oxygen deficient phases of TiO2, known as Magneli phases. ...
Defects or charge transfer: Different possibilities to explain the photoluminescence in crystalline Ba(ZrxTi1-x)O-3
(Elsevier B.V., 2016-11-01)
In this work, BZT (Ba (ZrxTi1-x)O-3), composite ceramic powder with x=0, 0.25, 0.50, 0.75 and 1 (mol) was prepared by the microwave-assisted hydrothermal method. The structural, morphological and optical properties of the ...
Geometric, Electronic, and Magnetic Properties of MgH2: Influence of Charged Defects
(American Chemical Society, 2016-10)
A study on the effect of the presence of charged vacancy on the electronic and magnetic properties of perfect magnesium hydride is presented. To this aim spin polarized ab initio calculations for the MgH2 structure containing ...
Quantum charge pumping in graphene-based devices: when lattice defects do help
(American Institute of Physics, 2013-09)
Quantum charge pumping, the quantum coherent generation of a dc current at zero bias through time-dependent potentials, provides outstanding opportunities for metrology and the development of nanodevices. The long electronic ...
Nilpotent orbits and codimension-2 defects of 6d N = (2, 0)theories
(2013-02-10)
We study the local properties of a class of codimension-2 defects of the 6d N = (2, 0) theories of type J = A, D, E labeled by nilpotent orbits of a Lie algebra $g, where g is determined by J and the outer-automorphism ...

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 ...
