| Outline of Final Research Achievements |
Usefulness of the Molecular Quantum-dot Cellular Automata (MQCA) device as a next-generation processing device was investigated by computer simulation. The model QCA device was constructed from a combination of one four-nuclear Ru mixed-valence complex and three sets of two input charges. It was found that 10 of all 16 logic gates work correctly. Processing speed of this model device is estimated as 10**15 times/s, and this value corresponds to the THz order of CPU clock speed. These results mean that there is a possibility that the MQCA device is superior to the present device.
