Probing Optical Response and Surface Conductance in Mixed-Halide Perovskites Using Terahertz Spectroscopy.
Mixed halide perovskite single crystals (MHPSCs) have attracted considerable attention as promising building blocks for next-generation photovoltaic technologies due to their exceptional optoelectronic properties, low fabrication cost, and facile processability. However, their practical implementation remains limited b...
