Polarity‐Controlled Coexistence of Electrochemical Metallization and Valence Change Mechanisms in a Unified Metal Halide Perovskite Memristor

ABSTRACT Metal halide perovskites (MHPs), owing to their mixed ionic‐electronic conductivity and defect‐tolerant lattice, have emerged as promising candidates for next‐generation memristors. Yet, the interplay of distinct resistive switching mechanisms remains poorly understood. Here, we provide direct experimental evi...

Crossover From Excitonic to Bulk Emission in Metal Halide Perovskite Nanocomposites

Perovskite nanocomposites have emerged as an effective strategy to overcome instability of metal‐halide perovskites (MHPs) by embedding nanocrystals (NCs) within host matrices while preserving their optoelectronic properties. However, this approach often results in morphologically heterogeneous systems with broad s...

Inducing Tunable Volatile Analog Switching in Nanocomposite-Based MAPbBr3 Perovskite Memristors for Synaptic Emulation.

Metal halide perovskites (MHPs) are promising candidates for memristive applications owing to their mixed ionic-electronic conductivity, yet their inherent instability and tendency toward abrupt resistive switching remain critical barriers to neuromorphic implementations. Here, we present a nanocomposite strategy in wh...
