Note: Graphene has special electrical properties that make them promising candidates for future nanoelectronics. While graphene, a one-dimensional layer of carbon, is a conductive material, it can be converted into a semiconductor in the form of nanowires. This means that it has a sufficient energy—or band gap—where no electronic state exists—it can be turned on and off, and thus may become a key component of nanotransistors.
The role of graphene nanosheets (GA) in the construction of nanotransistor (Nano Transistor) in the form of an electric field created by the gate electrode controls the current created by the source and drain electrodes. Drain current transport is modulated by changing the density of charge carriers in the two-dimensional transport channel. In the multi-layer Si graphene field effect nano transistor, a 3D channel of drain current is modulated by the thickness of the 3D channel . In the circuit diagram of a GA multi-layer graphene field effect nano-transistor, the source and drain electrodes are directly connected to the semiconductor, while the gate electrode is capacitively connected to the semiconductor using a gate dielectric.
Many chemical and physical methods have been proposed to produce different types of multilayered nanographene. The basis of the work of physical methods is that in these methods, they try to eliminate the forces between the graphene sheets in graphite and by separating them, they reach single layers of graphene or graphene oxide, which is the same top -down method. Is. In chemical methods, multi-layered nanographene is made by placing individual carbon atoms together, which is also called the bottom-up method. Graphene, a one-dimensional layer of carbon, is a conductive material, but it can be converted into a semiconductor in the form of nanowires. This means that it has a sufficient energy—or band gap—where no electronic state exists—it can be turned on and off, and thus may become a key component of nanotransistors.
