Description

Superlattice to Nanoelectronics provides a historical overview of the early work performed by Tsu and Esaki, to orient those who want to enter into this nanoscience. It describes the fundamental concepts and goes on to answer many questions about todays 'Nanoelectronics'. It covers the applications and types of devices which have been produced, many of which are still in use today. This historical perspective is important as a guide to what and how technology and new fundamental ideas are introduced and developed. The author communicates a basic understanding of the physics involved from first principles, whilst adding new depth, using simple mathematics and explanation of the background essentials. Topics covered include * Introductory materials * Superlattice, Bloch oscillations and transport * Tunneling in QWs to QDs * Optical properties: optical transitions, size dependent dielectric constant, capacitance and doping * Quantum devices: New approaches without doping and heterojunctions - quantum confinement via geometry and multipole electrodes. Issues of robustness, redundancy and I/O. Researchers, course students and research establishments should read this book, written by the leading expert in nanoelectronics and superlattices.

About the author

Raphael Tsu

Dr. R. Tsu started his professional career at the Bell Telephone Laboratories, Murray Hill, NJ, 1961, working on the theory and experiments related to electron-phonon interaction in piezoelectric solids. He became a close collaborator of Leo Esaki (Nobel Laureate in 1973) at IBM T.J. Watson Research Center where he joined in 1966, working on theory and experiments of optical- and transport-properties, band structures, in solids, and material characterization. A man-made semiconductor superlattice and modulation doping were conceived jointly with Esaki, in 1969, which led to a rapid development of man-made quantum materials and quantum structures eventually evolved into the present day quantum dots. His original formulation of tunneling through multiple man-made heterojunctions is widely accepted in nearly all aspects of resonant tunneling devices reaching Tera-Hertz, thus far being the fastest device to date. The theory and experiments of man-made superlattices and resonant tunneling through a quantum well led to his outstanding contribution award from IBM Research in 1975 and later in 1985, to sharing the International New Materials Prize of the American Physical Society with Esaki and Chang. In 1979, he became the head of Materials Research at Energy Conversion Devices, Inc., in charge of the study on the formation and structure of amorphous silicon. His major contributions involve the determination of bond angle distribution from Raman scattering and optical absorption measurements and experimental determination of conductivity percolation. In 1985, he became the head of the amorphous silicon research group at the Solar Energy Research Institute (now NREL) as a principal scientist, working on amorphous Si/Ge and Si/C alloys, showing that the famous Tauc's plot may be theoretically derived without adjustable parameters. In 1975, as the recipient of the Alexander von Humboldt award, he took a year sabbatical at Max Planck Institute for Solid State Physics in
