Abstract

This study explores the fabrication and characterization of environmentally friendly 2D tin lead perovskite memristors using the scalable technique of blade coating. Memristors, a new type of electrical component, only theoretical until recently, offer non-volatility and resistive switching properties, making them suitable for memory applications. Perovskite materials, such as tin lead perovskites, exhibit desirable characteristics like high ON/OFF current ratios and low power consumption, making them ideal for memristor fabrication. The prepared memristors have a smooth surface with a root-mean-square roughness of 0.4 nm, ensuring reproducibility and scalability. Spectral analysis reveals high absorbance in the mid-visible to UV wavelengths, indicating a bandgap energy of approximately 2.068 eV. The memristors demonstrate reliable performance, with good hysteresis within voltage-current graphs stable for up to 38 days, and maximum current On/Off ratios reaching up to 348. These findings highlight the potential of 2D tin lead perovskite memristors in neuromorphic computing, memory applications, and advanced electronics. Further research options include comparative analyses of different materials, fine-tuning fabrication techniques, and exploring lead-free alternatives.
