Graphene is an ideal two-dimensional crystal with regular six square symmetry, which has been discovered in recent years by covalent bonding of single layer carbon atoms. is a new type of low dimensional carbon material after fullerene and CNTs. Because of the extraordinary electrical, thermal and mechanical functions of graphite and broad application prospects, graphene is considered to be strategically
New materials have rapidly become the most active research frontier in the fields of material science and condensed State physics. In this paper, the experimental test, numerical simulation and theoretical analysis of the mechanical properties of graphene are first introduced.
With solid polystyrene as carbon source, the double treatment of copper foil by mechanical polishing and electrochemical polishing is a substrate, the results of the research on controllable growth of graphene by CVD method. The graphene was characterized by optical microscope, atomic force microscope, Raman spectroscopy, optical transmission spectrum, scanning tunneling microscope and field emission scanning electron microscope.
Composed of one layer of single atom structure carbon material, the most characteristic is that the light transmittance is better than the traditional CMOS sensor, and there will be good imaging performance in low illumination environment. Graphite sensor Another feature is thin, as we all know, Nokia 808 thickness is achieved. 9mm, the lens position is a large bulge, and the stone graphite ink sensor can let the next generation using 4100W PureView lens of the mobile phone do thinner, in addition, the production of graphite sensor is simpler than CMOS, And the materials are cheaper.
