We present the optical properties of Na<Subscript>0.7</Subscript>CoO<Subscript>2</Subscript> single crystals, measured over a broad spectral range as a function of temperature (T). The capability to cover the energy range from the far-infrared up to the ultraviolet allows us to perform reliable Kramers-Kronig transformation, in order to...</subscript></subscript>
