Fluoropolymers are of prime interest as solution processable materials for electronic applications such as embedded capacitors, multilayer capacitors, and high-energy-density capacitors. Herein, for the first time, we ...
Ferroelectric tunnel junction memory devices made from monolayers of vinylidene fluoride oligomers
Conductance bistability in Pt/Si–vinylidene fluoride (VDF) oligomer–Au ferroelectric tunnel junction devices is demonstrated. I–V and C–V measurements reveal bistable conductance switching within biasing voltage of ±0.5V ...
Thin SnO2 nanowires with uniform diameter as excellent field emitters : a stability of more than 2400 minutes
The stability of a field-emission event, i.e., the stability of the emission current over a long period of time, against thermal effects, etc., is one of the key factors for its application in real devices. Although ...
Enhancing electrochemical reaction sites in nickel–cobalt layered double hydroxides on zinc tin oxide nanowires : a hybrid material for an asymmetric supercapacitor device
Conducting nanowires are of particular interest in energy-related research on devices such as supercapacitors, batteries, water splitting electrodes and solar cells. Their direct electrode/current collector contact and ...

Dodecyl sulfate-induced fast faradic process in nickel cobalt oxide–reduced graphite oxide composite material and its application for asymmetric supercapacitor device
In this contribution, we report a facile preparation method of nickel cobalt oxide–reduced graphite oxide (NiCo2O4–rGO) composite material. A fast Faradic process has been realized by sodium dodecyl sulfate (SDS)-induced ...
Enhancing charge-storage capacity of non-volatile memory devices using template-directed assembly of gold nanoparticles
We demonstrate the controlled fabrication of aggregates of gold nanoparticles as a means of enhancing the charge-storage capacity of metal–insulator–semiconductor (MIS) devices by up to 300% at a low biasing voltage of ±4 ...
