Infochemistry

Infochemistry: Information Processing at the Nanoscale,
defines a new field of science, and describes the processes,
systems and devices at the interface between chemistry and
information sciences. The book is devoted to the application of
molecular species and nanostructures to advanced information
processing. It includes the design and synthesis of suitable
materials and nanostructures, their characterization, and finally
applications of molecular species and nanostructures for
information storage and processing purposes.

Divided into twelve chapters; the first three chapters serve as
an introduction to the basic concepts of digital information
processing, its development, limitations and finally introduces
some alternative concepts for prospective technologies. Chapters
four and five discuss traditional low-dimensional metals and
semiconductors and carbon nanostructures respectively, while
further chapters discuss Photoelectrochemical photocurrent
switching and related phenomena and self-organization and
self-assembly. Chapters eight, nine and ten discuss information
processing at the molecular level, and eleven describes information
processing in natural systems. The book concludes with a discussion
of the future prospects for the field.

Further topics:

• Traditional electronic device development is rapidly
  approaching a limit, so molecular scale information processing is
  critical in order to meet increasing demand for high computational
  power

• Characterizes chemical systems not according to their chemical
  nature, but according to their role as prospective information
  technology elements

• Covers the application of molecular species and nanostructures
  as molecular scale logic gates, switches, memories, and complex
  computing devices

This book will be of particular interest to researchers in
nanoelectronics, organic electronics, optoelectronics, chemistry
and materials science.

Infochemistry, the science at the interface between chemistry and the information sciences, follows the potential use of molecular switches in advanced information processing and storage. Where traditional transistors are reaching their limits in miniaturization due to interconnectivity and material issues, molecular information processing could be the key to satisfying our ongoing need for increasing computational power. This book describes the processes, systems and devices employed in infochemistry, and characterizes chemical systems according to their role as potential elements in information technology. It includes:

• Theory of Information
• Limitations of traditional devices
• Low-Dimensional Metals and Semiconductors
• Carbon and Carbon-Rich Nanostructures
• Photocurrent switching and related phenomena
• Supramolecular assembly
• Molecular scale electronics, logic gates and computing systems
• Bioinspired and biomimetic logic devices
  Presenting a unique combination of chemistry and information technology, Infochemistry: Information Processing at the Nanoscale defines this new field of science, and its future possibilities for advanced information processing.
