DOI: 10.1007/s10853-018-3009-6
Abstract: The investigation of hot-pressed methylammonium lead bromide (MAPbBr3) is reported. The as-prepared materials consisted of microcrystallites (30–500 μm size) with a non-centrosymmetric pseudo-cubic tetragonal crystalline structure (P4 mm space group). The thermal analysis under air showed a… read more here.
