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.

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.
