Abstract: Carbon transistor devices having channels formed from carbon nanostructures, such as carbon nanotubes or graphene, and having charged monolayers to reduce parasitic resistance in un-gated regions of the channels, and methods for fabricating carbon transistor devices having charged monolayers to reduce parasitic resistance. For example, a carbon field effect transistor includes a channel comprising a carbon nanostructure formed on an insulating layer, a gate structure formed on the channel, a monolayer of DNA conformally covering the gate structure and a portion of the channel adjacent the gate structure, an insulating spacer conformally formed on the monolayer of DNA, and source and drain contacts connected by the channel.

Abstract: Kohlenstoff-Transistoreinheiten, die Kanäle aufweisen, die aus Kohlenstoff-Nanostrukturen ausgebildet sind, wie zum Beispiel Kohlenstoff-Nanoröhren oder Graphen, und die geladene Monoschichten aufweisen, um den parasitären Widerstand in Bereichen der Kanäle ohne Gate-Steuerung zu verringern, und Verfahren zum Fertigen von Kohlenstoff-Transistoreinheiten, die geladene Monoschichten aufweisen, um den parasitären Widerstand zu verringern. Beispielsweise beinhaltet ein Kohlenstoff-Feldeffekttransistor einen Kanal, der eine Kohlenstoff-Nanostruktur aufweist, die auf einer Isolationsschicht ausgebildet ist, eine Gate-Struktur, die auf dem Kanal ausgebildet ist, eine Monoschicht aus DNA, die die Gate-Struktur und einen Abschnitt des Kanals angrenzend an die Gate-Struktur konform bedeckt, ein Isolationsabstandselement, das konform auf der Monoschicht aus DNA ausgebildet ist, und Source- und Drain-Kontakte, die durch den Kanal verbunden werden.
