Physics and Chemistry of Nano-structured Materials

Shihe Yang

Nanostructured materials represent a fast-evolving application of recent research in physics and chemistry. The core of this book consists of lectures by five noted researchers - Paul Alivisatos, D.D. Awschalom, Sumio Iijima, Charles Lieber, and Phaedon Avouris - presented at the Advanced Study Institute in Hong Kong. Discussions cover metal and semiconductor nanostructures, carbon nanostructures, functional nanostructured materials, and nanocomposites, including nanocrystals, tubes, and wires, semiconductor heterostructures, and manipulation and fabrication techniques. Anyone with an interest in the growth and characterization of sophisticated materials will find this a valuable resource.
