ABSTRACT

This introduction presents an overview of the key concepts discussed in this book. The book provides some ideas about the optical and electrical properties of semiconducting and metallic materials at the nanoscale, and then discusses some real-life applicational opportunities for fabricating devices. The book discusses basic quantum mechanics to understand the behavior of microscopic particles such as electrons and holes. It introduces the concept of quantum theory of radiation. Nanotechnology starts with quantum dots (QDs), defined as nanoparticles exhibiting three-dimensional quantum confinements, which leads to the development of many unique optical and transport properties depending on their shape and size. The physics of nanopiezotronics is based on the principle of a nanogenerator that converts mechanical energy into electric energy. The book highlights the fundamental ideas as well as ground-breaking applications of nano which will amaze the whole world.
