Opis

This book provides an introduction to the physics of nanoelectronics, with a focus on the theoretical aspects of nanoscale devices. The book begins with an overview of the mathematics and quantum mechanics pertaining to nanoscale electronics, to facilitate the understanding of subsequent chapters. It goes on to encompass quantum electronics, spintronics, Hall effects, carbon and graphene electronics, and topological physics in nanoscale devices.

Theoretical methodology is developed using quantum mechanical and non-equilibrium Green's function (NEGF) techniques to calculate electronic currents and elucidate their transport properties at the atomic scale. The spin Hall effect is explained and its application to the emerging field of spintronics - where an electron's spin as well as its charge is utilised - is discussed. Topological dynamics and gauge potential are introduced with the relevant mathematics, and their application in nanoelectronic systems is explained. Graphene, one of the most promising carbon-based nanostructures for nanoelectronics, is also explored.

• Begins with an overview of the mathematics and quantum mechanics pertaining to nanoscale electronics
• Encompasses quantum electronics, spintronics, Hall effects, carbon and graphene electronics, and topological physics in nanoscale devices
• Comprehensively introduces topological dynamics and gauge potential with the relevant mathematics, and extensively discusses their application in nanoelectronic systems

Recenzje

"This book will enable Physics and Engineering students to understand the most important underlying physics of modern nanoelectronics." --Prof Jian-Ping Wang, Director for The Center for Micromagnetic and Information Technologies (MINT), University of Minnesota, USA

"We can see in this book that in the fields of spintronics and graphene, science and technology are close to each other; fancy ideas from pure theory can be directly measured or even be used for applications. The role of gauge theory and topological structure is emphasized in this book." --Prof Shuichi Murakami, Tokyo Institute of Technology, Japan

"An excellent contribution to the fast-expanding field of nano-electronics. It is my pleasure to recommend this book to all researchers and students who are working in the field." --Prof Yong Jiang, University of Science and Technology Beijing, China
