Abstract

© 2022, The Minerals, Metals & Materials Society.This study focuses on the utilization of composite material for the active layer of memristors, which are used in memory devices and resistive switching applications. In this context, composite ink was produced using multi-walled carbon nanotubes (CNTs) and sodium alginate. The electrical characterization of the fabricated memristor indicates the presence of the capacitive effect. Experimental results show that the DC offset voltage improves the memristive property related to the bow-tie hysteresis. Notably, the capacitance value decreased with increasing DC offset amplitudes. In addition, durability and retention tests have been carried out to assess the reliability of the memristors. Also, scanning electron microscopy (SEM) was used to examine the surface morphology of the composite ink, and Raman spectroscopy was used to investigate its chemical structure and molecular interactions.
