Molecular single electronics using DNA base Cytosine

Molecules are essentially potential candidates for replacing silicon in the nanoelectronic circuits. As the size of devices is being scaled down single electron effects become prominent and will be the governing technology in the futuristic integrated circuits. DNA the life sustaining molecule is a promising candidate for molecular electronics. In this paper the DNA base Cytosine is studied for its electronic properties. The current-voltage characteristics are obtained for the molecule. The characteristics display excellent ON/OFF switching pattern that can be tuned using gate bias. The Cytosine molecule can be used to design molecular logic gates and memories.
