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.
This book is a review of the science and technology of the element carbon and its allotropes: graphite, diamond and the fullerenes. This field has expanded greatly in the last three decades stimulated by many major discoveries such as carbon fibers, low-pressure diamond, and the fullerenes. The need for such a book has been felt for some time. These carbon materials are very different in structure and properties. Some are very old (charcoal), others brand new (the fullerenes). They have different applications and markets and are produced by different segments of the industry.Few studies are available that attempt to review the entire field of carbon as a whole discipline. Moreover these studies were written several decades ago and a generally outdated since the development of the technology is moving very rapidly and scope of applications is constantly expanding and reaching into new fields such as aerospace, automotive, semiconductors, optics, and electronics. In this book the author provides a valuable, up-to-date account of both the newer and traditional forms of carbon, both naturally occurring and man-made. This volume will be a valuable resource for both specialists in, and occasional users of carbon materials.
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.
