This course text provides comprehensive coverage for fundamental and advanced courses in nanoelectronics. It provides insight into the future of electronics, emerging devices, logic and memory, sensors, systems architecture, nanofabrication, and the fundamental physics behind nanoelectronics. After reading the book, students will be able to understand the applications and design principles of nanodevices and nanosensors. The content is organised into nine chapters, each covering a specific area and written in accessible language. The topics covered include physical and technological limitations of nano CMOS devices, quantum physics, simulation and modelling, nanofabrication, emerging logic and memory devices and application areas including nanoarchitectures, sensors, and transducers. The book is a core text for senior undergraduate and postgraduate courses in nanoelectronics, and a valuable reference for researchers, engineers and specialists in fields including electronic devices, solid-state physics and nanotechnology.
