A novel high-performance photodetector based on two-dimensional perovskite crystals with alternating interlayer cations
This patent addresses the existing challenges by introducing a novel two-dimensional bilayered lead-halide hybrid perovskite single crystal with an alternating cations in the interlayer (ACI) phase, specifically with the chemical formula GAMA₂Pb₂I₇ (where GA is guanidinium and MA is methylammonium).
