MoS2 Nanosheets for Top-Gate Nonvolatile Memory Transistor Channel



original image

Top-gate ferroelectric memory transistors with single- to triple-layered MoS2 nanosheets adopting poly(vinylidenefluoride-trifluoroethylene) [P(VDF-TrFE)] are demonstrated. The nonvolatile memory transistor with a single-layer MoS2 channel exhibits excellent retention properties for more than 1000 s, maintaining ~5 × 103 for the program/erase ratio and displaying a high mobility of ~220 cm2/(V·s).
