Fluorene attachment to graphene and MoS2 monolayers: impact on electronic and optical properties

Abstract

The effect of fluorene adsorption on the electronic and optical properties of graphene and MoS₂ monolayers was investigated. The fluorene—graphene and fluorene—molybdenum disulfide binding energies were estimated and the energy band structures and absorption coefficients were calculated using the density functional theory. Specific features of the atomic structure and physicochemical properties of the 2D layers after attachment of fluorene molecules are demonstrated.
