Controlling screw dislocation evolution towards highly homogeneous quasi-two-dimensional (BA)2(MA)n−1PbnI3n+1 single crystals for high-response photo-detectors

The response of planar photodetectors is enhanced by controlling the growth of a series of (BA) 2 (MA) n −1 Pb n I 3 n +1 SCs by macroscopic screw dislocation.
