Discovery of one-dimensional material carbon nanotubes in 1991 by the Japanese physicist Dr. Sumio Iijima has resulted in voluminous research in the field of carbon nanotubes for numerous applications, including possible replacement of silicon used in the fabrication of CMOS chips. One interesting feature of carbon nanotubes is that these can be metallic or semiconducting with a bandgap depending on their diameter. In search of non-classical devices and related technologies, both carbon nanotube-based field-effect transistors and metallic carbon nanotube interconnects are being explored...
