Abstract
The DNA-based logic circuit has emerged as a potential member for the next-generation ultralow power application due to its rapid self-assemble technique, enormous parallelism, compatibility with various organic and inorganic molecules, and energy efficiency. Density functional theory coupled with non-equilibrium Green’s function-based first principle approach is used in the investigation of quantum scattering transmission property of a single-strand DNA-based logic device using silicon carbide nanotube as electrodes at room temperature. The single-strand DNA nano-logic circuit exhibits high tunneling current in forward and reverse bias conditions for ± 1 V bias voltages. This proposed model can be exploited as bio-inspired logic circuit in future generation devices due to its satisfactory current–voltage response and the nature of resistance.
