An ab initio study of several hybrid improper ferroelectric (HIF) materials in the Ruddlesden–Popper phases and double perovskite structures is here presented. The focus is on the correlation between the electric field gradient at several nuclear s

The effect of substituting Ca by Cd in several Ca3B2O7 Ruddlesden–Popper (RP) and double perovskite (DP) CaCdB2O6 systems, where B is Mn or Ti, is here deeply investigated through ab initio calculations. We show that these cation substitutions have

This paper presents ab initio calculations on stability properties and phase diagrams of Ca- and Cd-related hybrid improper ferroelectric materials, with the Ruddlesden–Popper (RP) and double perovskite (DP) structures. The results show that enthal

The oxygen octahedral rotations in ${\mathrm{Ca}}_{2}\mathrm{Mn}{\mathrm{O}}_{4}$, the first member of the $\mathrm{Ca}\mathrm{O}{({\mathrm{CaMnO}}_{3})}_{n}$ Ruddlesden-Popper family, is probed through a set of complementary techniques, including te

The structural phase transition path from the low-temperature polar structure up to the highest symmetric phase in the hybrid improper ferroelectric ${\mathrm{Ca}}_{3}{\mathrm{Mn}}_{2}{\mathrm{O}}_{7}$ compound is here investigated at atomic scale. M

In the present study, we have determined the intrinsic refractive index of anodic aluminium oxide, which is originated by the formation of nanoporous alumina templates. Different templates have been fabricated by the conventional two-step anodization

In this manuscript we present a new type of hydrogen optical metamaterial sensor based on the fabrication of Pd dendritic nanostructures. The fabrication of the sensor relies on a cheap self-assembly process based on the pulsed electrodeposition meth
