Cover Story: Nanocarbon materials have the advantages of biocompatibility, thermal stability, and chemical stability and have shown excellent electrical properties in electronic devices. In this study, Al/MWCNT:GQD/ITO memristors with rewritable nonvolatile properties were prepared based on composites consisting of multiwalled carbon nanotubes (MWCNTs) and graphene quantum dots (GQDs). The switching current ratio of such a device can be tuned in two ways: by adjusting the ultraviolet light irradiation time and by adjusting the concentration of quantum dots. These findings lay a foundation in adjustable logic memory applications. View this paper.
