Versatile Metal Phthalocyanine-Based Memristive Nanowire Network: Unraveling the Dynamics of Digital to Analog Switching.

ABSTRACT: Organic memristors with tunable resistive switching (RS) are promising candidates for brain-inspired neuromorphic computing. This study reports a self-assembled organic nanowire network memristor based on copper (II) hexadecafluoro-phthalocyanine (F₁₆CuPc), exhibiting digital, multilevel, and analog switching through compliance current (I _CC) modulation. Current-voltage and impedance analyses reveal that the transition in RS behavior is primarily driven by a shift from trap-limited to trap-free space charge-limited conduction as I _CC increases. In low I _CC, Ag⁺-cation migration plays a central role in conduction through redox-assisted Ag-F/ Ag-π interwire interactions, causing abrupt switching. In contrast, higher
