Coplanar switching of polarization in thin films of vinylidene fluorideoligomers

Investigation of resistive switching in anodized titanium dioxide thin films

In this work, TiO2 nanostructures were grown on titanium thin films by electrochemical anodizing method. The bipolar resistive switching effect has been observed in Pt/TiO2/Ti device. Resistive switching characteristics indicated the TiO2 nanotubes are one of the potential materials for nonvolatile memory applications.  Increasing anodizing duration will increase nanotube lengths which itself c...

Pyroelectric study of polarization switching in Langmuir-Blodgett films of poly(vinylidene fluoride trifluoroethylene)

Ferroelectric Switching of Vinylidene and Trifluoroethylene Copolymer Thin Films on Au Electrodes Modified with Self-Assembled Monolayers

The ferroelectric switching characteristics of a vinylidene fluoride and trifluoroethylene copolymer were significantly changed via the chemical modification of a gold electrode with an alkanethiol self-assembled monolayer (SAM). The alkanethiol SAM-Au electrode successfully suppressed the leakage current (dark current) from the electrode to the bulk ferroelectric. Smaller leakage currents led ...

Effect of thermal annealing on ferroelectric domain structures in poly(vinylidene-fluoride-trifluorethylene) Langmuir-Blodgett thin films

Effect of thermal annealing on ferroelectric domain structures in poly(vinylidene-fluoride-trifluorethylene) Langmuir-Blodgett thin films" (2014). Stephen Ducharme Publications. Paper 95. We report a piezo-response force microscopy study of the effect of thermal annealing on ferroelec-tric domain structures in 6 to 20 monolayer (11 to 36 nm) polycrystalline poly(vinylidene-fluoride-trifluorethy...

Revisiting the δ-phase of poly(vinylidene fluoride) for solution-processed ferroelectric thin films.

Ferroelectric poly(vinylidene-fluoride) (PVDF) has, in the past, been proposed as an ideal candidate for data storage applications as it exhibits a bistable, remanent, polarization that can repeatedly be switched by an electric field. However, fabrication of smooth ferroelectric PVDF thin films, as required for microelectronic applications, is a long-standing problem. At present, the copolymer ...
