Abstract Owing to the increasing interest in nonvolatile memory devices, resistive switching based on hybrid nanocomposite of a 2D material, molybdenum disulphide (MoS 2 ) and polyvinyl alcohol (PVA) is explored this work. As proof concept, we have demonstrated fabrication device with configuration PET/Ag/MoS -PVA/Ag via an all printed, hybrid, state art approach. Bottom Ag electrodes, active layer MoS -PVA top electrode are deposited by reverse offset, electrohydrodynamic (EHD) atomization...
