Space electric field concentrated effect for Zr:SiO2 RRAM devices using porous SiO2 buffer layer

To improve the operation current lowing of the Zr:SiO2 RRAM devices, a space electric field concentrated effect established by the porous SiO2 buffer layer was investigated and found in this study. The resistive switching properties of the low-resistance state (LRS) and high-resistance state (HRS) in resistive random access memory (RRAM) devices for the single-layer Zr:SiO2 and bilayer Zr:SiO2/...

Large Electric Field–Enhanced–Hardness Effect in a SiO2 Film

Silicon dioxide films are extensively used in nano and micro-electromechanical systems. Here we studied the influence of an external electric field on the mechanical properties of a SiO2 film by using nanoindentation technique of atomic force microscopy (AFM) and friction force microscopy (FFM). A giant augmentation of the relative elastic modulus was observed by increasing the localized electr...

Local electric field screening in bi-layer graphene devices

*Correspondence: Olga Kazakova, National Physical Laboratory, Quantum Detection, Hampton Road, Teddington TW11 0LW, London, UK e-mail: [email protected] We present experimental studies of both local and macroscopic electrical effects in uniform single(1LG) and bi-layer graphene (2LG) devices as well as in devices with non-uniform graphene coverage, under ambient conditions. DC transport m...

Multilayers for high-To superconducting electric field effect devices

Epitaxial multilayers, consisting of a PrBa2Cu307_ x buffer layer, ultrathin YBa2Cu307_ x and SrTiO 3, have been grown for application in electric field effect devices. Different analytical techniques indicate a sharp interface between the layers and good dielectric properties of the SrTiO3-1ayer. First measurements show clear modification of the superconductor's current-voltage characteristics...
