Abstract

In the original version of the manuscript, the k-vectors used in the calculation of the effective masses have been incorrectly multiplied by a factor of a/2π (where a is the lattice constant). This induced too small effective masses across all systems. The correct effective masses are given in Table 1 below. 1 Table Calculated hole and electron effective mass (×m0) along Γ–X of BA2PbBr4 and BA2PbI4 with and without SOC effects at the GGA/PBE level using VASPKIT code (Table presented.) It is noted that these effective masses are found to be on the order of 0.2-0.3 m0; these values are close to those previously determined experimentally (Refs. 31 and 32 of the original manuscript) and theoretically (Refs. 33 and 34) for 3D MHPs, but larger than previous predictions for similar 2D MHPs (Ref. 35). Also, the 0.13 m0 value calculated along the Γ–X direction in BA2PbI4 is comparable with what has been determined experimentally for bulk MAPbI3, 0.10 m0 (Ref. 31). This correction does not affect in any significant way the conclusions of the article. The authors apologize for any inconvenience caused.
