Fabrication of stable low voltage organic bistable memory device

Two-terminal resistive switching memory devices with a polymer film embedded with nanoparticles

“…When PS was replaced with poly(methyl methacrylate) (PMMA) as the matrix, the electrical behavior of the single-layer device was almost same. 45,57,63,64 Other insulating polymers, such as polyimide and polyvinylpyrrolidone, were also used as the matrix. 46,47,53,55,60 Conjugated polymers were investigated to substitute the insulating polymer and organic semiconductor, because conjugated polymers are semiconductive as well.…”

Organic Bistable Switching Memory Devices with MeH-PPV and Graphene Oxide Composite

“…As shown in the energy level band diagram (Fig. 2(c)) [11,12], the highest occupied molecular orbital (HOMO) and the lowest unoccupied molecular orbital (LUMO) of MeH-PPV occur at 5.4 and 3.2 eV, respectively. In the active layer of MeH-PPV:GO, the energy difference between the work function of Al and LUMO of MeH-PPV (1.1 eV) is higher than the energy difference between the work function of ITO and HOMO of MeH-PPV (0.6 eV ).…”

Focused Role of an Organic Small-Molecule PBD on Performance of the Bistable Resistive Switching

“…The mechanism of the resistive switching based on PBD:PMMA nanocomposite can be explained by the trap and detrap of electrons in the PBD material. Electrons are injected from the Al electrode to LUMO of PMMA during forward sweep, by means of tunneling mechanism through PMMA molecules [15], which fill the traps of PBD to fulfill the write process at positive bias. During reverse bias, the electrons captured by the trap of PBD are detrapped and released into the PMMA matrix by Fowler-Nordheim tunneling into the Al electrode.…”

“…Transparent material, poly(methyl methacrylate) (PMMA), is used to manufacture various illuminant equipments, optical glass, and optical fiber. For ORRAM, inorganic materials as reported cover quantum dots [13, 14], such as CuInS 2 -ZnS core-shell quantum dots and thiol-capped CdS quantum dots, oxide nanoparticles (NPs) ZnO [15], and carbon nanomaterials like graphene, CNTs, and fullerene together with its derivatives [16–21], which can be embedded into the insulator-like matrix PMMA.…”
