Quantum Nanoelectronics is the first textbook to handle important growth, including adiabatic quantum computing, nanoelectronic aspects of ink-printed thin film solar cells, nanostructured electrodes, solar water splitting, and convenient hydrogen storage, thereby suggesting profitable new directions for nanoelectronic technology. Expanded tutorial coverage is provided for aspects of molecular electronics, from the basics of electronic conduction through chemical bonds to a sixteen-bit computing device. The reader, whether student or professional, is encouraged to use simple theoretical models and to return to the entrepreneurial approach of the pioneers in the Moore's Law revolution.
