Nanoscale QCA-based logic gates in graphene technology

摘要

QCA assemblies, in which basic cells are formed on the basis of graphene in order to provide a coupling field distribution in the form of an electrostatic field, a magnetic field, and the like which allows a unique association between field distribution and logic state. Moreover, the corresponding energy structure may be selected so as to allow operation of the QCA assemblies at ambient temperature. Hence, the signal processing capabilities of QCA assemblies may be obtained at significantly reduced complexity compared to conventional quantum-based QCA assemblies, which typically operate at very low temperatures.

1. A cellular automata assembly for processing a signal, comprising:
a first basic cell comprising a first graphene layer defining a first carbon nanotube used to induce a first coupling field distribution; and a second basic cell positioned adjacent to said first basic cell and comprising a second graphene layer defining a second carbon nanotube used to induce a second coupling field distribution, said first and second basic cells interacting with each other by said first and second coupling field distributions so as to determine a logic state of the signal.
