چکیده

Resistive memory effect has been found in carbon nanostructure-based devices by Standley et al. Nano Lett. 8, 3345 2008 . Compared to nanostructures, hydrogenated amorphous carbon a-C:H has much more controllable preparation processes. Study on a-C:H-based memory is of great significance to applications of carbon-based electronic devices. We observed nonvolatile resistance memory behaviors in metal/a-C:H /Pt structures with device yield 90%, ON/OFF ratio 100, and retention time 105 s. Detailed analysis indicates that the resistive switching originates from the formation/rupture of metal filaments due to the diffusion of the top electrodes under a bias voltage. © 2010 American Institute of Physics. doi:10.1063/1.3406121

Dual-functional Memory and Threshold Resistive Switching Based on the Push-Pull Mechanism of Oxygen Ions

The combination of nonvolatile memory switching and volatile threshold switching functions of transition metal oxides in crossbar memory arrays is of great potential for replacing charge-based flash memory in very-large-scale integration. Here, we show that the resistive switching material structure, (amorphous TiOx)/(Ag nanoparticles)/(polycrystalline TiOx), fabricated on the textured-FTO subs...

Resistive switching of alkanethiolated nanoparticle monolayers patterned by electron-beam exposure.

Carbon-based electronic devices are promising candidates for complementing silicon-based electronics in memory device applications. For example, sputtered thin films of amorphous carbon exhibit memristive behavior. The reported devices, however, have a minimal active area of about 50 nm diameter, leading to large set currents in the μA range. Although power efficiency would benefit from reduced...
