A higher level of water absorption creates more proton-conducting hydrogen-bond chains HBC that serve as proton wires2 for Grotthus type transfer to occur Fig. We will interpret your continued use of this site as your tranistor of our use of cookies. The simulations are in good agreement with the experimental data at low Vds, while the nonlinear dependence of Ids on Vds for higher Vds is not reproduced.

In maleic-chitosan nanofibres, the flow of protonic current is turned on or field-effectt by an electrostatic potential applied to a gate electrode. Export in format suitable for direct import into delicious.

We used a 8.

However, in highly conducting proton wires, such as in gramicidin, the activation energy associated with transport is very small5. This paper has 42 citations. CiteULike organises scholarly or academic papers or literature and provides bibliographic which means it makes bibliographies for universities and higher education establishments. Recently, conducting polymer ion bipolar junction transistor devices have been demonstrated25, Delivery of Cargo with a Bioelectronic Trigger.

We also estimate Ids as a function of Vds for different Vgs Fig. In hybrid bionanodevices, biological multifunctionality has been added to carbon nanotubes21 or silicon nanowires22 with transmembrane proton conductive proteins.

Coherence resonance in a single-walled carbon nanotube ion channel. Field–effect authors declare no competing financial interests.

Anomalous ion transport in 2-nm hydrophilic nanochannels. RoudsariAdnan KapetanovicM. As expected for a semiconducting FET with predominantly positive charge carriers, a negative Vgs results in a higher sourcedrain current for the same Vds, whereas a positive Vgs almost turns Ids off. In maleic-chitosan nanofibres, the flow of protonic current is turned on or off by an electrostatic potential applied to a gate electrode.

To calculate the gate capacitance, we first obtained the interface charge at different gate biases; whereas the two other contacts were kept at zero bias.
