Overview of Few Layer Graphene Few layer graphene refers to a type composed of 3-10 layers of carbon atoms that are periodically and closely packed in a benzene ring structure (that is,hexagonal honeycomb structure)stacked in different stacking methods (including ABC stacking,ABA stacking,etc.)Two-dimensional carbon material. Singlelayer graphene powder has a two-dimensional structure of a new carbonaceous material. Graphene powder has excellent electrical, thermal and mechanical properties.
What is the applications of Few Layer Graphene With the gradual breakthrough of mass production and large-size problems, the industrial application of graphene is accelerating.Based on existing research results,the first commercial applications may be mobile devices,aerospace,and new energy. Battery field.Graphene has a special significance for basic research in physics.It enables some quantum effects that can only be demonstrated theoretically before can be verified through experiments.In two-dimensional graphene,the mass of electrons does not seem to exist.This property makes graphene a rare condensed matter that can be used to study relativistic quantum mechanics - because massless particles must move at the speed of light Therefore,it must be described by relativistic quantum mechanics,which provides theoretical physicists with a new research direction:some experiments that originally needed to be carried out in giant particle accelerators can be carried out with graphene in small laboratories.Zero energy gap semiconductors are mainly single-layer graphene,and this electronic structure will seriously affect the role of gas molecules on its surface.The function of single-layer graphene's enhanced surface reactivity compared with bulk graphite is demonstrated by the results of graphene hydrogenation and oxidation reactions,indicating that the electronic structure of graphene can modulate its surface activity. In addition, the electronic structure of graphene can be correspondingly changed by the,induction of gas molecule adsorption,which not only changes the concentration of carriers,but also can be doped with different graphenes. 1.Sensor Graphene can be made into a chemical sensor.This process is mainly done through the surface adsorption properties of graphene. According to the research of some scholars,the sensitivity of graphene chemical detectors can be compared with the limit of single molecule detection. Graphene's unique two-dimensional structure makes it very sensitive to the surrounding environment.Graphene is an ideal material for electrochemical biosensors. Sensors made of graphene have good sensitivity for detecting dopamine and glucose in medicine. 2.Transistor Graphene can be used to make transistors.Due to the high stability of the graphene structure, this type of transistor can still work stably on the scale of a single atom.In contrast,the current silicon-based transistors will lose their stability on the scale of about 10 nanometers; the ultra-fast reaction speed of electrons in graphene to the external field makes the transistors made of it can reach Very high operating frequency.For example, IBM announced in February 2010 that it would increase the operating frequency of graphene transistors to 100 GHz,which exceeds that of silicon transistors of the same size.
