Zwitterions in 3D Perovskites: Organosulfide-Halide Perovskites [PDF]
Journal of the American Chemical Society, 2022 Although sulfide perovskites usually require high-temperature syntheses, we demonstrate that organosulfides can be used in the milder syntheses of halide perovskites. The zwitterionic organosulfide, cysteamine (CYS; +NH3(CH2)2S-), serves as both the X- site and A+ site in the ABX3 halide perovskites, yielding the first examples of 3D organosulfide ...

Persistence of the Jahn–Teller distortion of Mo5+ in double perovskites : a structural study of Ba2NdMoO6 and the effect of chemical doping in Ba2Nd1xYxMoO6 [PDF]
, 2010 The cation ordered perovskites Ba2NdMoO6 and Ba2Nd1-xYxMoO6 have been structurally characterised by a combination of neutron and X-ray powder diffraction. Ba2NdMoO6 retains the tetragonal room temperature structure on cooling to 150 K[: I4/m; a = 5.98555(

Electrical Properties of Un-doped and Doped EuTiO3-based Perovskites [PDF]
, 2013 Un-doped and doped EuTiO3 (ET) ceramics were prepared in 5%H2/95%N2 and N2 atmospheres at various temperatures (1350, 1450 and 1500 oC). For un-doped ET, higher pellet density (above 90%) and larger grain sized ceramics were obtained from the higher ...

Narrowband Monolithic Perovskite–Perovskite Tandem Photodetectors [PDF]
Advanced Optical Materials, 2022 AbstractNarrowband photodetectors (PDs) are sought after for many applications requiring selective spectral response. The most common systems combine optical bandpass filters with broadband photodiodes. This work reports a method to obtain a narrowband response in a perovskite PD by the monolithic integration of a perovskite photoconductor and a ...

Layered Perovskites Enhanced Perovskite Photodiodes
The Journal of Physical Chemistry Letters, 2021 Recently, two-dimensional layered perovskites have emerged as effective additives for stabilizing conventional three-dimensional metal halide perovskites. With the addition of layered perovskites, the perovskite-based devices also exhibited enhanced optoelectronic properties, such as reduced nonradiative recombination and ionic migration, strengthened ...
