Although the graphene sheet has been studied theoretically for many years, most of the early works were conducted to understand the electronic properties of bulk graphite and related materials. We have designed nanostructured materials using graphene as well as fullerenes and nanotubes as building blocks of new, hierarchical materials for more than two decades. Graphene with periodic structural modifications was predicted to possess semiconducting electronic structure depending on the relative orientation and the lattice-constant ratio of the original graphene lattice and the newly introduced periodicity. After the experimental production of graphene and other atomic-layer materials, many two-dimensional systems have been extensively studied theoretically and experimentally together with their one-dimensional counterparts, nanotubes, because of their rich electronic properties. We show that, by utilizing strain, stacking sequence of layers, and curvature and chirality of nanotubes, one can modify and engineer the electronic transport properties of atomic-layer materials.

Biography of Susumu Saito:
Susumu Saito is a Professor of Physics at the Tokyo Institute of Technology. He studied Applied Physics (B.S. and M.S.) from Tokyo University (1976-1982) and Applied Physics (Ph.D.) at Tokyo University (1982-1986). He worked at the University of California, Berkley in 1987 as a research associate in the Department of Physics. His field of research focuses on organic chemistry including synthetic organic chemistry, molecular recognition chemistry, main-group organometallic chemistry, asymmetric catalysis and design of protonic acid catalysts. In 2011 Dr. Saito was named a Fellow of the American Physical Society for major contributions to the theoretical understanding of low-dimensional systems and nano-structures. Since 2013 Dr. Saito has been the Director of the International Research Center for Nanoscience and Quantum Physics at the Tokyo Institute of Technology.
