Complex oxide functionality, such as ferroelectricity, magnetism or superconductivity is often achieved in epitaxial thin-film geometries. Oxygen vacancies tend to be the dominant type of defect in these materials but a fundamental understanding of t

With the slowing down of Moore’s law, related to conventional scaling of integrated circuits, alternative technologies will require research effort for pushing the limits of new generations of electronic or photonic devices. Perovskite oxides with

Thin films of amorphous (a)-TiO2 are ubiquitous as photocatalysts, protective coatings, photoanodes and in memory application, where they are exposed to excess electrons and holes. We investigate trapping of excess electrons and holes in the bulk of

Density Functional Theory (DFT) calculations demonstrate that holes can trap in crystalline and amorphous HfO2 and Al2O3 in both single- and bipolaron states. Polarons in the crystalline phase have small trapping energies of the order of 0.2 eV. In t

Using Density Functional Theory (DFT) calculations we modeled the mechanisms of formation of oxygen vacancies and interstitial ions in amorphous HfO2 under electron and hole injection conditions. The results demonstrate that injected electrons and ho

We review the current understanding of intrinsic electron and hole trapping in insulating amorphous oxide films on semiconductor and metal substrates. The experimental and theoretical evidences are provided for the existence of intrinsic deep electro

We used density functional theory (DFT) calculations to study the interaction of hydrogen with amorphous hafnia ($\mathrm{a}\text{\ensuremath{-}}{\mathrm{HfO}}_{2}$) using a hybrid exchange-correlation functional. Injection of atomic hydrogen, its di

How small nanodiamonds can be is a crucial question for biomedical applications. To answer this question, we present here molecular dynamic simulations of the annealing of very small diamond clusters (diameter between 0.3 and 1.3 nm) of various shape
