Optical properties of graphene and IV–VI semiconductors L A Falkovsky DOI: 10.1070/PU2008v051n09ABEH006625 Contents 1. Click here to close this overlay, or press the "Escape" key on your keyboard. Reflectance and transmittance of graphene in the optical region are analyzed as a function of frequency, temperature, and carrier density. Some features of the site may not work correctly. Dielectric function of IV–VI semiconductors in the optical range 890 5. Nonlinear optical properties of multilayer graphene in the infrared. A narrow gap and the linearity of the electron spectrum, which are common features of these materials, are responsible for a singularity of the dielectric function (logarithmic in the real part and step-like in the imaginary part) at the threshold of direct interband transitions and, accordingly, for an anomalously large permittivity in IV–VI semiconductors. ) to study the graphene optical properties [4].

The frequency dispersion of the dynamic conductivity of graphene, of a multilayer graphene, and of IV–VI semiconductors is considered as a function of the temperature and carrier density in the range of frequencies that are higher than the carrier relaxation rate but are lower than the conduction band width. Introduction 887 2. The band structure and thus optical properties of GO depend on the oxygen group coverage and are harder to predict than for graphene or graphite , . Semantic Scholar is a free, AI-powered research tool for scientific literature, based at the Allen Institute for AI. Consequently, the optical properties of the reduced GO (r-GO) vary between the different reduction methods depending on residual oxygen group coverage and defects within the carbon sheets. The graphene transmittance in the optical range is frequency-independent and its departure from unity yields the value of the fine structure constant.
