Investigation of Quantum Ballistic Transport in Single Strand DNA with Silicon Carbide Nanotube: A High performance Embedded System

DNA has emerged as a strong candidate for nextgeneration ultra-low power applications due to its self-assembly technique. First principle calculations associated with Density Functional Theory (DFT) and Non-Equilibrium Green’s Function (NEGF) analytical method is used for the study of scattered transmission characteristics into the quantum confined DNA strands via Silicon Carbide (SiC) Nanotube (NT) electrodes at 300K. This phenomenon shows that the conductivity of the central molecular region of SiC NT embedded DNA strand has increased and a large number of current flows through the molecular channel. A low HOMOLUMO gap increases the sensitivity of the scattering central molecular channel. The electrical doping process helps to increase the sensitivity of the molecular channel. The sensitivity of the DNA increases satisfactorily.
