Formation and stabilization of all-inorganic perovskites for photovoltaics

All-inorganic perovskite films hold promise for improving stability of perovskite solar cells. However, the desirable narrow-bandgap inorganic perovskites (such as CsPbI3 and CsPbI2Br) are suffering from the thermodynamic phase instability, as the photoact ...

Helium-induced electronic transitions in photo-excited Ba+–Hen exciplexes

Marcel Drabbels

The possibility for helium-induced electronic transitions in a photo-excited atom is investigated using Ba+ excited to the 6p 2P state as a prototypical example. A diabatization scheme has been designed to obtain the necessary potential energy surfaces and ...

Precursor adsorption efficiency of titanium tetra isopropoxide in the presence of a barium beta-diketonate precursor

Patrik Willi Hoffmann, Yury Kuzminykh, Michael Oliver Reinke

Barium titanate is a promising candidate for integrated photonic application due to its high electro-optic coefficient; therefore the need arises for a suitable deposition technique which provides high film quality at low temperatures (below 500 degrees C) ...

Barium Ions and Helium Nanodroplets: Solvation and Desolvation

Marcel Drabbels, Xiaohang Zhang

The solvation of Ba+ ions created by the photoionization of barium atoms located on the surface of helium nanodroplets has been investigated. The excitation spectra corresponding to the 6p 2P1/2

Implication of the Acid-Base Properties of V/Ti-oxide Catalyst in Toluene Partial Oxidation

Albert Renken, Lioubov Kiwi, Fabio Rainone

The work presents the effect of K-doping on V/Ti-oxides taking into account: the surface acid–base properties and the structure of surface vanadia species in respect to the catalyst performance and deactivation. The structure of active surface species dete ...

Electrochemical promotion of an IrO2 catalyst for the gas phase oxidation of ethylene

This work contributes to the generalization of the Non-faradaic Electrochemical Modification of Catalytic Activity effect, known under the acronym NEMCA. This effect is observed for the first time over an oxide catalyst, namely IrO2 supported on yttria-sta ...

Effect of Structural-Changes in Complex Perovskites on the Temperature-Coefficient of the Relative Permittivity

Nava Setter, Enrico Colla

The dielectric behavior and structure of the Sr(Zn1/3Nb2/3)O3-Ba(Zn1/3Nb2/3)O3 solid solution have been investigated with the intention of understanding the relationship between the structural changes and the temperature coefficient of the relative permitt ...
