Abstract: In this paper, an active terahertz modulator based on optically controlled organometal halide perovskite MAPbI2Br is proposed. The terahertz wave time-domain transmission of the MAPbI2Br/Al2O3 sample was measured by a terahertz time-domain spectrometer. Experimental results… read more here.
