In the case of green electronics, pectin has emerged as a suitable alternative to toxic metal oxides for resistive switching applications. Herein, a pectin-based thin film was fabricated on a fluorine-doped tin oxide glass substrate for RS mechanism. The presence of sp³-C groups with low binding energy corresponds to tunable charged defects and the oxygen vacancies confirmed by the O 1s spectra that plays a decisive role in the resistive switching mechanism, as revealed by X-ray photoemission spectroscopy (XPS). The surface morphology of the pectin film shows homogeneous growth and negligible surface rougRSC advancesGreen thin film for stable electrical switching in a low-cost washable memory device: proof of concept.PMC8694386RG-1438-089Arshad NAbbasi MSAhmed IIrshad MSUr Rehman SAhmad SAl Firdausi MDJaved MQSharaf MfalseGreen thin film for stable electrical switching in a low-cost washable memory device: proof of concept.Low-cost and washable resistive switching (RS) memory devices with stable retention and low operational voltage are important for higher speed and denser non-volatile memories.
