Joining of Graphene by Particle Beam Irradiation and Its Properties
Graphene joining can be used to control the shape and area of the original graphene, and obtain the graphene based microelectronic component. In this chapter, the method of particle beam (laser and ion beam) irradiation method was proposed to join graphene. The ion and laser beam irradiation were experimentally proved to be able to join two overlapped graphene. The different mechanisms by these two types of particle beams were discovered. It was found that there were always defects in the butt joint, which easily raise concentration of stress during stretch, and these defects were determined by the relative deflection angle of two sheets. The relationship between the mechanical properties and the irradiated ion dose, energy and type was discovered, and it was proposed that the electronic transport properties of the butt joint were heavily blocked by the difference of individual orbital energy and localized state induced by defects.
