Abstract: Herein, radiowave/microwave bandpass/reject filters are fabricated from the tungsten doped Bi1.5Zn0.92Nb1.5‐6x/5WxO6.92 (W‐BZN) pyrochlore ceramics. The W‐BZN band filters are prepared by the solid state reaction technique and subjected to X‐ray diffraction (XRD) and impedance spectroscopy… read more here.

Abstract: Abstract The structure and dielectrics properties of (Bi1.5Zn0.5)(Zn0.5Nb1.5-xRux)O7 (BZNR) pyrochlore ceramics were investigated. The pyrochlore ceramics were prepared by solid-state methods. The XRD results indicate that all ceramics exhibit single cubic pyrochlore structure. The crystal… read more here.

DOI: 10.1103/physrevb.101.121115
Abstract: The optical properties of Sn-doped Bi1.1Sb0.9Te2S, the most bulk-insulating topological insulator thus far, have been examined at different temperatures over a broad frequency range. No Drude response is detected in the low-frequency range down to… read more here.
