We constructed a continuum theory of carbon phases based on the Landau theory of phase transitions. Our theory ties up many seemingly unrelated data on the carbon system. Transformations between graphite, diamond, and liquid-carbon are described by the Landau–Gibbs free-energy which depends on two order parameters: crystallization and structural. The barrier-height and gradient-energy coefficients...
Carbon is often considered to be silicon of the future because of the unique properties resulting from the variety of possible structural forms. A wide range of electronic properties of carbon yields many possible applications. Classical thermodynamics successfully describes bulk equilibrium of the diamond-graphite system in a wide range of temperatures and pressures. Equilibrium in the carbon system...
The optical constants n (refractive index) and k (extinction coefficient) of CVD (chemical vapor deposition) diamond thin films are important parameters not only for their optical applications but also provide information concerning the microstructure of the films. Values of n and k as well as the rms surface roughness σ have been extracted from experimental data on transmittance and reflectance for...
