a Schematic of the STCAD growth apparatus. b Photographs of the as-grown MAPbBr3 single crystals. c Measured and calculated X-ray diffraction patterns of differently oriented wafers. The insets show the processed wafers with the same thickness of 1 mm. d Crystal structure diagram of MAPbBr3 viewed along the c axis. e Crystallographic geometric configurations of the (100), (110), and (111) planes of MAPbBr3 cubic lattice. (dark gray ball for lead atom, magenta ball for bromine atom, and agminated brown ball for methylamine molecule).
