Evaluation of Nanostructured NiS₂ Thin Films from a Single-Source Precursor for Flexible Memristive Devices.

ABSTRACT: Herein, we report the first demonstration of a single-step, in situ growth of NiS₂ nanostructures from a single-source precursor onto a flexible substrate as a versatile platform for an effective nonvolatile memristor. The low temperature, solution-processed deposition of NiS₂ thin films exhibits a wide band gap range, spherical-flower-like morphology with high surface area and porosity, and negligible surface roughness. Moreover, the fabricated Au/NiS₂/ITO/PET memristor device reveals reproducible bipolar resistive switching (RS) at low operational voltages under both flat and bending conditions. The flexible device shows stable RS behavior for multiple cycles with a good memory window (∼10²) and data retention of up to 10⁴ s.
