Abstract
Graphene is a really single atom thick two-dimensional film consisting of only carbon atoms and exhibits very interesting material properties such as massless Dirac-fermions, Quantum Hall effect, very high electron mobility as high as 2×106 cm2/Vsec. A. K. Geim and K. S. Novoselov had prepared this film by exfoliating from HOPG and put it onto SiO2 substrate with the help of Scotch-Tape at year of 2004. And at the same time, they clearly showed the electric field effect by making a graphene device. Since then, graphene has been regarded as a post-silicon material all over the world and vast number of researchers had started to do research by paying attention on its physics and device operation. Here in this report, I shall briefly show the above mentioned trend in graphene reseach.
