Abstract: Narrow‐bandgap (NBG) tin (Sn)–lead (Pb) perovskites generally have a high density of unintentional p‐type self‐doping, which reduces the charge‐carrier lifetimes, diffusion lengths, and device efficiencies. Here, a p–n homojunction across the Sn–Pb perovskite is demonstrated,… read more here.

Abstract: The effects of barium ions non-stoichiometry on the phase composition, microstructure, and microwave properties of Ba1+xCo2V2O8 (x = 0–0.5) ceramics were studied. XRD results show that the single phase of BaCo2V2O8 was found in the composition of… read more here.
