    • was born in Montreal, Canada, in 1963. He obtained a B.S.c. in physics from Imperial College, London, in 1984, and a Ph.D. in physics from Copenhagen University in 1988. His doctoral research focused on X-ray diffraction studies of phase transitions on semiconductor surfaces, and was carried out at the Hamburg Synchrotron Radiation Laboratory with the support of the Max Planck Institute for Solid State Research in Stuttgart. From 1988 to 1991 he was a post-doctoral researcher at Risø; National Laboratory in Denmark, studying theoretical and experimental aspects of crystalline epitaxy, as well as investigating the fractal nature of cauliflowers and other vegetables. He joined the Aono Atomcraft Project in 1991. He is also a regular contributor to the Science and Technology section of “The Economist”.

Abstract

Japan is launching an ambitious ten-year nanotechnology project, the goal of which is the “ultimate manipulation of atoms and molecules”. An important aspect of this project is the use of the scanning tunneling microscope (STM) to modify materials on the nanometer scale. Another five-year Japanese project devoted entirely to STM-controlled atom-scale fabrication is already nearing completion. Japanese industrial laboratories have also produced some outstanding results in this area of research. This article reviews recent Japanese efforts in STM-based nanotechnology and attempts to put these in a worldwide perspective.
