Ebook: Introduction to nanoelectronic single-electron circuit design

In Introduction to Nanoelectronic Single-electron Circuit Design, single-electron circuits are studied as an introduction to the rapidly expanding field of nanoelectronics. Treated are both the analysis and synthesis of circuits with the nanoelectronic metallic single-electron tunneling (SET) junction device. The basic physical phenomena under consideration are the quantum mechanical tunneling of electrons through a small insulating gap between two metal leads, the Coulomb blockade, and Coulomb oscillations - the last two resulting from the quantization of charge. While electron transport in nanoelectronic devices can best be described by quantum physics; nanoelectronic circuits can best be described by Kirchhoff's voltage and current laws. The author employs an unconventional approach in explaining the operation and design of single-electron circuits. All models and equivalent circuits are derived from first principles of circuit theory. This is a must if we want to understand the characteristics of the nanoelectronic devices and subcircuits. Besides this, a circuit theoretical approach is necessary for considering possible integration in current and future IC technology. Based on energy conservation, in circuit theory connected to Tellegen's theorem, the circuit model for single-electron tunneling is an impulsive current source. Modeling distinguishes between bounded and unbounded currents. The Coulomb blockade is explained as a property of a tunnel junction, not of an island. Read more...
