- In this research we have studied physisorption of hydrogen molecules on armchair (3,3) boron-nitride nanotube using density functional methods. Optical properties of the boron-nitride nanotube, with and without adsorbed H₂ molecules, were investigated under parallel and perpendicular polarized electric fields. The results indicate that the nanotube optical gap slightly changes due to H₂ physisorption and increasing H₂ physisorption suppresses the boron-nitride nanotube optical spectrum. Also, the nanotube gets more transparent as the H₂ concentration increases, in other words boron-nitride nanotube dielectric function decreases. Anisotropic dielectric function is another result which is determined by random phase approximation method.
