TL;DR: In this paper, the structural properties of iodide/chloride mixed-halide perovskites and correlating them with their photovoltaic performances were investigated, and they found that, independent of the components ratio in the precursor solution, Cl incorporation in an iodide-based structure, is possible only at relatively low concentration levels (below 3-4%).

TL;DR: A characterization via X-ray diffraction and high-resolution transmission electron microscopy and second-derivative analysis of the absorption spectra allowed to determine the size dependence of seven transitions in the absorption spectrum; some of these transitions were identified on the basis of their normalized confinement energy.

TL;DR: In this paper, high-resolution transmission electron microscopy (TEM) and X-ray diffraction (XRD) was carried out on Ga2O3 epilayers grown at low temperature (650 °C) by vapor phase epitaxy in order to investigate the real structure at the nanoscale.

TL;DR: In this paper, a new lipophilic etheramide ligand was obtained in high yield from the reaction of p-t-butylcalix[4]arene with α-chloro-N,N-diethyl acetamide.

TL;DR: The crystal structure and ferroelectric properties of ε-Ga2O3 deposited by low-temperature MOCVD on (0001)-sapphire were investigated by single-crystal X-ray diffraction and the dynamic hysteresis measurement technique.
