Transmission electron microscopy (TEM) and Scanning TEM (STEM) have recently seen a dramatic improvement in instrumentation with the emergence of hardware aberration correction. However, imperfections in the preparation of TEM samples often become the limiting factor of the information to be obtained. For example, Nano-materials, as well as biological molecules are typically prepared across support films for imaging by the electron beam. Graphene has renewed interest in crystalline TEM supports, because it provides supports of single atom thickness, extreme physical stability, periodic structure, and excellent electrical and thermal properties. Recently, we developed and reported a technique for growing the high crystalline quality and the lagre-scale graphene films using chemical vapour deposition (CVD). These results can expect application as effective crystalline TEM supports. In the present study, first we have synthesized graphene films with very good crystal quality. Their domain sizes were more than a few hundred nano-meters. Also, we have evaluated their detailed nanostructure characteristics by using High Resolution TEM and EELS (Electron Energy-Loss Spectroscopy) spectrum.
