The 2H phase and 1T coexisting in the same molybdenum disulfide (MoS 2 ) nanosheets can influence electronic properties of materials. MoS is introduced into 2H‐MoS by two‐step hydrothermal synthetic methods. Two types nonvolatile memory effects, namely write‐once read‐many times rewritable effect, are observed flexible devices with configuration Al/1T@2H‐MoS ‐polyvinylpyrrolidone (PVP)/indium tin oxide (ITO)/polyethylene terephthalate (PET) Al/2H‐MoS ‐PVP/ITO/PET, respectively. It that...
