The principal aim of nanoelectronics is to process, transmit and store information by taking advantage of properties of matter that are distinctly different from macroscopic properties. Nanoelectronics is used in the fabrication of nanostructures for semiconductor applications, packaging technology etc. It has potential application in retaining and improving the industrial competitiveness, primarily in industrial sector. This book is an attempt to make the reader familiar with nanoelectronics and also make them aware of the impending advancements in the world of technological development.
