The International Symposium on the Science and Technology of Mesoscopic Structures was held at
Shin-Kohkaido in Nara from November 6-8 1991. The symposium was sponsored by the International
Institute for Advanced Study and partly by Nara Prefecture Nara City Nara Convention Bureau
and the Ministry of Education Science and Culture of Japan as well as industrial
organizations. We would like to acknowledge the support of the symposium by these or
ganizations. The scope of the symposium was planned by the organizing committee to cover
outstanding contributors in the fields of (1) ballistic transport (2) electron wave guides and
interference effects (3) quantum confinement effects (4) tunneling phenomena (5) optical
nonlinearity and (6) fabrication technology of meso scopic structures. Twenty-six invited
speakers were selected from the United States Europe and Japan. In addition twenty-four
contributed papers were accepted for presentation at the poster session. These papers are
included in the proceedings. We are grateful to the organizing committee Ms. Y oshiko Kusaki
of the Inter national Institute for Advanced Study for the secretarial service and Dr. Nobuya
Mori Osaka University for his scientific cooperation. Thanks are also due to the authors and
the participants for their contributions to a successful symposium.
