Influence of 2D CuxAl(100−x) electrodes on the CuxAl(100−x)/Cu21(SiO2)79/W memristive device

Abstract

In recent years, 2D metal nanomaterials have emerged as a novel class of 2D materials owing to their unique physiochemical properties. In this paper, memristive devices ([Formula: see text](BE)/[Formula: see text]/W(TE)) were fabricated utilizing 2D [Formula: see text] materials with different compositions as electrodes. After exfoliation by sonication, the minimum thickness of the freestanding single layer of 2D [Formula: see text] was only 1.5 nm. Furthermore, the distribution of SET thresholds was determined by the composition of the 2D [Formula: see text] materials. The results suggest that the SET and RESET thresholds can be adjusted according to the composition of the 2D [Formula: see text] materials. The application of 2D metals as electrodes is promising for miniature memristive devices.
