Silicene nanoribbon as a new DNA sequencing device

Highlights: • The possibility of DNA sequencing is investigated for silicene nanoribbon. • Changes in the transmission caused by adsorption of each nucleobase. • Calculations done within the DFT method using the non-equilibrium Green's function approach. - Abstract: The importance of applying DNA sequencing in different fields, results in looking for fast and cheap methods. Nanotechnology helps this development by introducing nanostructures used for DNA sequencing. In this work we study the interaction between zigzag silicene nanoribbon and DNA nucleobases using DFT and non equilibrium Green's function approach, to investigate the possibility of using zigzag silicene nanoribbons as a biosensor for DNA sequencing.
