Viologen phosphoric acid salt modified PEDOT:PSS for high‐performance 3D perovskite photodetectors

open access: yesInfoMat, Volume 7, Issue 12, December 2025.
A novel viologen derivative, APV, is incorporated into PEDOT:PSS to enhance the performance of 3D perovskite photodetectors. The optimized device achieves an ultra‐low dark current of 5.75 × 10−7 mA cm−2 and a large bandwidth of 1.5 MHz. Integrated into an optical wireless communication system, it achieves a data rate of 12.5 Mbps, demonstrating ...

High SNR BER Comparison of Coherent and Differentially Coherent Modulation Schemes in Lognormal Fading Channels

open access: yes, 2014
Using an auxiliary random variable technique, we prove that binary differential phase-shift keying and binary phase-shift keying have the same asymptotic bit-error rate performance in lognormal fading channels.
