Incorporation of SnO2 nanoparticles in PMMA for performance enhancement of a transparent organic resistive memory device

“…5a). 10,12,13,18,31 The results indicate that the captured carriers in SnO 2 NPs embedded PMMA matrix can act as space charges. The electron mobility value of SnO 2 NPs blended PMMA thin lm is found to be 1.3 Â 10 À12 m 2 V À1 s À1 by using the following eqn (2)…”

“…5(a). 2,10,13,14,29,31 Moreover, (I-V) curve at very low applied bias (0 to À0.45 V) in the HRS could be tted by using TE process, as shown in inset of Fig. 5(a).…”

“…Some fundamental investigations about the RS mechanisms in OBDs using the synthesized inorganic nanoparticles blended in the insulating organic layer have been studied. [26][27][28][29][30] Carrier transport mechanism in OBDs utilizing hybrid organic/ inorganic nanocomposites have been explained typically by space-charge-limited-current (SCLC), 10,13,19,29,[31][32][33][34] ionic conduction, 35 ohmic conduction, 10,12,18,20 hopping conduction 36 and Fowler-Nordheim (FN) tunnelling, 37,38 including thermionic emission (TE). 11,12,18 Furthermore, a systematic study on the RS mechanisms and switching parameters (current ON/OFF ratio, SET/RESET voltage, endurance and retention time) are needed to enhance device efficiency.…”

Triggering WORM/SRAM Memory Conversion by Composite Oxadiazole in Polymer Resistive Switching Device

“…Polymethyl methacrylate (PMMA) has been verified a polymeric matrix in resistive switching application [30,31], which being a low cost and easily processed organic material, has more and more interest in flexible resistive switching devices owing to its favourable switching and for its function as a normative resistance material in submicron RRAM lithography [32]. Simultaneously, oxadiazole derivatives were intensively reported as ideal electron acceptor materials in electronic devices [33][34][35][36][37][38][39]; 2-(4-tert-butylphenyl)-5-(4biphenylyl)-1,3,4-oxadiazole was one of the most efficient electron-transporting materials on account of its high electron affinity. In the present work, PMMA is used as the host body for forming a thin film.…”

Synthesis and memory characteristics of highly organo‐soluble hyperbranched polyimides with various electron acceptors

“…Different from the traditional inorganic silicon‐based technologies, which information is stored based on charging and discharging of the silicon‐cells, for polymer memory devices, information is stored based on the transition of polymer active layer from low‐conductivity state (OFF) to high‐conductivity state (ON) induced by an external electric field. Various types of polymer materials including conjugated polymers, functional polyimides (PIs) and complex systems have been developed for memory applications …”
