Tip: Graphene, which is made up of just one carbon atom, can be used to create multi-layered graphene nanoparticles that use less energy and take up less space.
Graphene is a semiconductor material with zero and unsuitable chat for logic circuits, but using nanotechnology, they create different forms of this material that have different chats. Graphene nanofibers, multi-layered graphene and graphene grown on Si are among these forms. The term nano-transistor is derived from the combination of the term nanoscale in transmission and resistance. In a Si graphene nanoscale transistor, the resistance between two electrodes can be transmitted or controlled by a third electrode. Unlike a bipolar transistor, the third electrode is connected capacitively and is not in contact with the semiconductor. Three electrodes are connected to the source, drain and gate in the nanostructured structure of Si multi-layered graphene field effect.
In the orbital diagram, a multi-layered graphene field nanoparticle, two source electrodes, and a drain are directly connected to the semiconductor, while the gate electrode is capacitively connected to the semiconductor using a dielectric gate. The electric field created by the gate electrode controls the current generated by the two source electrodes and the drain. The drain current is modulated by changing the density of the load carriers in the two-dimensional transmission channel. In a transistor, the effect of a multi-layered graphene Si field is modulated by a three-dimensional drain current channel with a thickness of three-dimensional transmission channel. Numerous chemical and physical methods have been proposed for the production of various types of multi-layered nano-graphene. The basis of the work of physical methods is that in these methods try, the forces between the graphene plates in Eliminate graphite and separate it into single-layer graphene or graphene oxides, which is the same way from top to bottom. In chemical methods, multi-layered nano-graphene is made from the juxtaposition of individual carbon atoms, which is also called the bottom-up method.
Conclusion:
In the multi-layer peeling method of nano-graphene, the electronic quality of the layers is high, the cost of producing graphene in this method is low and does not require special equipment. In nano-transistors, the field effect using graphene (Si) is the number of nano-graphene layers produced by this single and multilayer method. One of the limitations of using this method is that it is not suitable for bulk production and the thin layers of production are non-uniform and uneven, and it is a time consuming method.
