Abstract

Large-scale colloidal synthesis and integration of uniform-sized molybdenum disulfide (MoS<sub>2</sub> ) nanosheets for a flexible resistive random access memory (RRAM) array are presented. RRAM using MoS<sub>2</sub> nanosheets shows a ≈10 000 times higher on/off ratio than that based on exfoliated MoS<sub>2</sub> . The good uniformity of the MoS<sub>2</sub> nanosheets allows wafer-scale system integration of the RRAM array with pressure sensors and quantum-dot light-emitting diodes.
