Colloidal Synthesis of Uniform‐Sized Molybdenum Disulfide Nanosheets for Wafer‐Scale Flexible Nonvolatile Memory

Large-scale colloidal synthesis and integration of uniform-sized molybdenum disulfide (MoS2 ) nanosheets for a flexible resistive random access memory (RRAM) array are presented. RRAM using MoS2 nanosheets shows a ≈10 000 times higher on/off ratio than that based on exfoliated MoS2 . The good uniformity of the MoS2 nanosheets allows wafer-scale system integration of the RRAM array with pressure sensors and quantum-dot light-emitting diodes.
