Facile coating of manganese oxide on tin oxide nanowires with high-performance capacitive behavior
In this paper, a very simple solution-based method is employed to coat amorphous MnO2 onto crystalline SnO2 nanowires grown on stainless steel substrate, which utilizes the better electronic conductivity of SnO2 nanowires ...
Wide-bandgap Zn2GeO4 nanowire networks as efficient ultraviolet photodetectors with fast response and recovery time
Ultraviolet (UV) photodetectors based on ternary Zn2GeO4 nanowire (NW) networks are demonstrated. The devices show fast response and recovery time, which is attributed to the unique NW-NW ...
Kinking-induced structural evolution of metal oxide nanowires into single-crystalline nanorings
We report an innovative method to fabricate single-crystalline nanorings based on the conventional vapor−liquid−solid (VLS) mechanism. The controllable formation of kinks in functional oxide nanowires (NWs) can be employed ...
Enhanced ferroelectric switching characteristics of P(VDF-TrFE) for organic memory devices
In the following work, we report an approach to shorten the ferroelectric switching time of P(VDF-TrFE) film by blending with as-synthesized gold nanoparticles. Ferroelectric hysteresis measurements give remnant polarization ...
Network-enhanced photoresponse time of Ge nanowire photodetectors
We demonstrated that the photoresponse time of Ge nanowire (NW) photodetectors could be greatly improved by using percolated NW networks (instead of single NW) as the active detection channels. Although the reset time for ...
Supercritical carbon dioxide-treated electrospun poly(vinylidene fluoride) nanofibrous membranes : morphology, structures and properties as an ionic-liquid host
A reverse-barrier technique is used to enable the treatment of electrospun poly(vinylidene fluoride) nanofibrous membranes with supercritical carbon dioxide. The treatment induces the formation of nanopores and extended-chain ...
Room-temperature synthesis of MnO2·3H2O ultrathin nanostructures and their morphological transformation to well-dispersed nanorods
MnO2·3H2O ultrathin nanostructures with sizes of 2–3 nm were synthesized at room temperature and transformation to well-dispersed nanorods was achieved after hydrothermal treatments.
Electrochemical energy storage in a β-Na0.33V2O5 nanobelt network and its application for supercapacitors
We report a nanostructured oxide pseudocapacitor electrode utilizing a sodium-doped vanadium oxide (β-Na0.33V2O5) nanobelt network with a three dimensional framework crystal structure, which has been successfully synthesized ...
Ultrahigh-performance solar-blind photodetectors based on individual single-crystalline In2Ge2O7 nanobelts
Solar-blind photodetectors are designed from individual In2Ge2O7 nanobelts using a standard photolithography technique. The detectors demonstrated high sensitivity and selectivity towards the solar-blind spectrum, fast ...
Alternative resistive switching mechanism based on migration of charged counter-ions within conductive polymers
In this paper, an alternative bi-stable resistive switching mechanism for non-volatile organic memory applications is reported. The memory device is formed from a sandwiched structure of Au/polyaniline:poly(4-styrenesulfonic ...
