One-dimensional (1D) nanostructures represent a group of nanomaterials with highly anisotropic morphologies, the smallest dimension falling in the range of 1–100 nm. Typical examples of 1D nanostructures include nanowires and nanotubes. Semiconductor nanowires are characterized by the efficient transport of electrons and excitons, and have been regarded as the most promising building block for nanoscale electronic and optoelectronic devices. Nanosystems can be built from these elements using metallic nanowires as interconnects. Carbon nanotubes, either semiconducting or metallic, are mechanically robust and chemically stable, suggesting numerous potential applications in nanoelectronics. The growth, characterization, and applications of 1D nanostructures invoke all disciplines of science and engineering. As a result, scientists working in one area need to go beyond their own expertise to obtain a broad view of the whole field. The objective of this book is to elucidate the fundamental, underlying science common to 1D nanostructures and their applications. The result is a representative snapshot of the latest developments from diverse perspectives in a series of chapters from highly engaged scientists. 

One-dimensional (1D) nanostructures, including nanowires, nanotubes and quantum wires, have been regarded as the most promising building blocks for nanoscale electronic and optoelectronic devices. This book presents exciting, state-of-the-art developments in synthesis and properties of 1D nanostructures with many kinds of morphologies and compositions as well as their considerable impact on spintronics, information storage, and the design of field-effect transistors.
