We have experimentally studied the dispersion of optical conductivity in few-layer graphene through reflection spectroscopy at visible wavelengths. A laser scanning microscope (LSM) with a supercontinuum laser source measured the frequency dependence of the reflectance of exfoliated graphene flakes, including monolayer, bilayer and trilayer graphene, loaded(More)
2 is the permittivity of free space, ε c is the complex relative permittivity, σ is the optical conductivity, and ω is the angular frequency of the incident monochromatic optical field. " should read: " Here, H and E are the magnetic and electric fields, respectively, ε 0 is the permittivity of free space, ε c = (n − ik) 2 is the complex relative(More)
