    Optoelectronic properties of graphene silicon nano-texture
    (2014) Brahmanandam, J.; Ajmalghan, M.; Abhilash, R.K.; Mahapatra, D.R.; Rahaman, M.R.; Hegde, G.M.
    Graphene on silicon with silicon dioxide quantum dots is a promising opto-electronic material. The optical band gap and the corresponding optical conductivity are estimated using the density functional approach with the combination of molecular dynamics. The regular repeating unit cell of graphene silicon nano-texture is identified using the classical molecular dynamics simulations. Electronic calculations predict the optical band gap is around 0.2 eV and the optical conductivity is identified to be 0.3 times the quantum conductance. � 2014 IEEE.
