Few examples of protonic-based devices exist, and include an ice FET working with AC current12, and a water bipolar junction transistor Transisotr the bias is reversed, the charge should be released and cause hysteresis in the Ids—Vds dependence.

CiteULike organises scholarly or academic papers or literature and provides bibliographic which means it makes bibliographies for universities and higher education establishments. In contrast, the development of computing has mainly focused on devices that control electronic currents such as vacuum tubes, solid-state fieldeffect transistors FETand nanoscale molecular structures8— From these plots, it is also clear that in significantly thinner devices the expected charge modulation will be higher.

Most chitin derivatives are biodegradable, nontoxic, and physiologically inert This suggests that highly efficient proton wires are formed in the material. Register and you can start organising your references online. We replaced the properties of silicon with those of the channel material. Protons Search for additional papers on this topic. 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.

Ion bipolar junction transistors. To create that charge, excess field-efvect are injected into the maleic—chitosan via the proton transparent contacts. The intra- and inter-molecular hydrogen bonds as well as the hydrogen bonds between the water of hydration and the polar parts of the molecule form a continuous network comprised by hydrogen-bond chains.
