Halide Perovskites: Kilogram‐Scale Crystallogenesis of Halide Perovskites for Gamma‐Rays Dose Rate Measurements (Adv. Sci. 2/2021)

In article number 2001882, Pavao Andricevic, Laszlo Forro, and co‐workers introduce the ‘oriented crystal‒crystal intergrowth’ method, yielding solution‐grown MAPbBr3 crystals with volume and mass of over 1000 cm3 and 3 kg. Its increased size, equipped with carbon electrodes, is utilized for sensitive gamma ray detection of a 60Co source at the dose rate up to 2.3 Gy h−1 at ambient conditions.
