A search for literature reporting the optical properties of carbon in any spectral region provided experimental data from which the extinction-coefficient for crystalline graphite could be determined in the 0.001 eV to 1.0 meV region. By use of high and low energy approximations the extinction-coefficient spectrum thus obtained was defined piecewise analytically over the entire spectral region. Kramers-Kronig analysis of the extinction-coefficient spectrum then gave spectral values of the real refractive index, which along with the extinction-coefficient made it possible to calculate the complex dielectric constant, the energy loss function and the reflectance at normal incidence. Analytical methods were used in all integrations of the Kramers-Kronig analysis and sum rules. Five sum rules were evaluated showing the high quality of the resultant data. These data are presented in graphical and tabular form.

"A study of the electronic properties of a substance usually requires the knowledge of its band structure. The starting point when trying to determine the band structure of a crystalline material is to employ one or another type of approximation to obtain the general form of the structure of energy bands. This general form usually contains certain parameters whose theoretical calculation is difficult or prohibitive. Thus we resort to experiments to determine the values of these parameters and consequently the exact band structure. To establish the validity of an approximation we have to show that the model based on this approximation can explain the physical properties of the material." --

This book provides an overview of electronic and optical properties of graphite-related systems. It presents a well-developed and up-to-date theoretical model and addresses important advances in essential properties and diverse quantization phenomena. Key features include various Hamiltonian models, dimension-enriched carbon-related systems, complete and unusual results, detailed comparisons with the experimental measurements, clear physical pictures, and further generalizations to other emergent 2D materials. It also covers potential applications, such as touch-screen panel devices, FETs, supercapacitors, sensors, LEDs, solar cells, photodetectors, and photomodulators.
