Infochemistry: Information Processing at the Nanoscale,defines a new field of science, and describes the processes,systems and devices at the interface between chemistry andinformation sciences. The book is devoted to the application ofmolecular species and nanostructures to advanced informationprocessing. It includes the design and synthesis of suitablematerials and nanostructures, their characterization, and finallyapplications of molecular species and nanostructures forinformation storage and processing purposes.
Divided into twelve chapters; the first three chapters serve asan introduction to the basic concepts of digital informationprocessing, its development, limitations and finally introducessome alternative concepts for prospective technologies. Chaptersfour and five discuss traditional low-dimensional metals andsemiconductors and carbon nanostructures respectively, whilefurther chapters discuss Photoelectrochemical photocurrentswitching and related phenomena and self-organization andself-assembly. Chapters eight, nine and ten discuss informationprocessing at the molecular level, and eleven describes informationprocessing in natural systems. The book concludes with a discussionof the future prospects for the field.
Further topics:
* Traditional electronic device development is rapidlyapproaching a limit, so molecular scale information processing iscritical in order to meet increasing demand for high computationalpower
* Characterizes chemical systems not according to their chemicalnature, but according to their role as prospective informationtechnology elements
* Covers the application of molecular species and nanostructuresas molecular scale logic gates, switches, memories, and complexcomputing devices
This book will be of particular interest to researchers innanoelectronics, organic electronics, optoelectronics, chemistryand materials science.
