WebWe have measured basal-plane reflectivity spectra of hexagonal graphite over the spectral range 0.5-3 eV at pressures up to 12 GPa (T=300 K). From the increase of the A 1 and A 2 … It delivers optical properties of graphite at normal incidence, which comply with the available measurements on HOPG from 10 K to room temperature and up to about λ = 200 μm. The model extends this range into the FIR and provides analytical expressions for all optical properties, from 0.3 to 10 000 μm. Zobraziť viac The far-infrared (FIR) Planck astronomical observatory was launched in 2009 and delivered, in 2011, a treasure trove of FIR Galactic emission data (Tauber et al. 2010; Planck … Zobraziť viac As explained above, all experimental optical properties of interest here can be deduced directly from any pair among the three quantities R, ϵ1 and σ for which Kuzmenko et al. (2008) gave experimental data up to 200 μm; … Zobraziť viac An essential basis of our work is the data measured or deduced by Kuzmenko et al. (2008), in the form of files kindly provided by A. Kuzmenko, … Zobraziť viac Absent experimental results beyond 200 μm, understanding the physics of electron transport in graphite is a prerequisite to a sensible continuation of the data of Kuzmenko et al. (2008) into the FIR. This is made far easier … Zobraziť viac
