One-dimensional semiconducting materials are expected to produce highly-efficient electronic components due to their extraordinary characteristics in applications like nanoscale electronics, biology, optoelectronics, and energy storage. Moreover, complex semiconducting materials have also been developed from nanowires using epitaxial growth mechanisms. The current application areas of nanowires include high-speed transistors, nanoelectronics, chemical- and biosensors, and LEDs (light-emitting diodes) with little power consumption. Concerns for the synthesis of these devices include inferior mobility and optical characteristics of nanomaterials materials. This book offers a thorough understanding of recent developments in synthesizing nanowires for constructing various types of electronic components. Especially, the book reviews the uses of nanowires in sensors, detectors, energy storage, circuits, and energy conversion, etc. Growth approaches of various types of nanowires are also discoursed along with the discussion of their electronic applications. Therefore, this book can be used as a ready reference by researchers, students, and teachers in the field of nanotechnology and electronics.
