Nano- and Micromaterials

Product Description

The future focus of nanotechnology will be on realizing new functions over greater scales. This book describes the creation of nano- and microscale structures and functions by controlling temperature, light, pressure, or carrier injections. It covers novel nano-integration technologies such as quantum-well devices possilbe by utilizing, for example, the self-organization of surface nanostructures and optically or pressure-induced phase transitions, micro machines using microstereolithography, as well as new techniques of laser spectroscopy and new computational methods for estimating atomic and electronic structures and their functions on the nano- and microscales.

Nanoelectronics and Information Technology

Product Description
Providing an introduction to electronic materials and device concepts for the major areas of current and future information technology, the value of this book lies in its focus on the underlying principles. Illustrated by contemporary examples, these basic principles will hold, despite the rapid developments in this field, especially emphasizing nanoelectronics.
There is hardly any field where the links between basic
science and application are tighter than in nanoelectronics & information technology. As an example, the design of resonant tunneling transistors, single electron devices or molecular electronic structures is simply inconceivable without delving deep into quantum mechanics.
This textbook is primarily aimed at students of physics,
electrical engineering and information technology, as well as material science in their 3rd year and higher. It is equally of interest to professionals wanting a broader overview of this hot topic.

“Nanoelectronics and Information Technology” by Rainer Waser and his colleagues is an outstanding compendium of
information about an exciting new field. Owing to its high quality and complete coverage of the many topics in this area, this well referenced book will have a long and very useful life as a primary text for students experienced and new in nanoelectronics. It is a very impressive book.” (Richard Siegel)

Spectroscopical investigation of carbon nanostructures: Singlewall and multiwall carbon nanotubes, carbon onions

Product Description
Carbon is the only element in the IV column to have both the sp2 and the sp3 bonding, and this allows it to have an allotropic form. Different carbon nanostructures with a different number of carbon atoms and geometrical shape can obtained.These imply different electronic properties according to the geometrical structures. They are smaller, longer, cleaner, and more chemically manipulable than the semiconducting or metallic counterparts up to now used. Novel photoemission spectroscopy investigations by a synchrotron radiation source have been performed on carbon nanostructures. Core level and valence band of single wall, multiwall, carbon onions have studied. Intercalation by potassium have been performed to observe how the electronic structures can be modified and in detail the Fermi edge. Our data show how a Luttinger liquid behaviour can be observed in the single wall carbon nanotubes,while for the multiwall carbon nanotubes a Fermi liquid behaviour can be assigned. A shift to higher binding energy and broadening of the core level upon the potassium intercalation has been observed as temperature of decomposition of singlewall.
