A general design strategy is presented for tuning the convergence of direct and indirect bandgaps based on chemical adjustment s- p-orbital character conduction band minimum.
We report the successful crystal growth of a previously unknown mixed-metal organic compound (CH<sub>3</sub>NH<sub>3</sub>)<sub>2</sub>AgInBr<sub>6</sub>.
Three new compounds have been added to the alkali chalcogenide and oxychalcogenide families: Sr2O2Bi2Se3, Ba2O2Bi2Se3, Sr2O2Sb2Se3 were synthesized by direct combination of SrO or BaO with Bi2Se3 Sb2Se3. The structure, determined from laboratory X-ray powder diffraction data, consists double chains edge-sharing BiSe4O square pyramids. Temperature-dependent resistance data reveal all three be insulators, while heat capacity Ba2O2Bi2Se3 in conjunction literature reports, low energy phonon...
We present an optimized seeded chemical vapor transport method for the growth of Cu2OSeO3 that allows control in a system with many stable phases to selectively produce large phase-pure single crystals. This is shown consistently crystals range 120 180 mg. A Wulff construction model representative crystal shows minimum energy surface {1 1 0}, followed by 0 0}. Analysis lowest index planes revealed cleavage Se–O bonds has cost, leading overall high energy. The demonstrated here promise other...
