Unveiling the Impact of Bi3+ Heterovalent Doping on the Negative Capacitance and Ionic Conductivity of Perovskite Single Crystals: Implication in Neuromorphic Computing

The introduction of heterovalent metal ion doping in the lead (Pb) halide perovskites presents a novel opportunity to manipulate the electronic and ionic properties by introducing dopant charges and increasing the carrier concentration in single crystals. While previous studies have reported on the use of bismuth (Bi
