Providing the first self-contained introduction to the physical concepts, techniques and applications of nanotechnology, this is of interest to readers grounded in college chemistry and physics. As such, it is suitable for students and professionals of engineering, science, and materials science and to research workers of varied backgrounds in the interdisciplinary areas that make up nanotechnology. The author covers the spectrum from the latest examples of nanoscale systems, quantum concepts and effects, self-assembled nanosystems, manufacturing, scanning probe methods of observation and fabrication, to single-electron and molecular electronics. In so doing, he not only comprehensively presents the scientific background, but also concludes with a look at the long-term outcomes.
