A study of energy gap, refractive index and electronic polarizability of ternary chalcopyrite semiconductors

A simple relation between the optical electronegativity, energy gap, refractive index and electronic polarizability is given for ternary chalcopyrite semiconductors. Energy gap has been evaluated from the optical electronegativity whereas refractive index and electronic polarizability values have been evaluated from the energy gap by proposing a linear relation between them. The calculated valu...

Defects, Impurities and Doping Levels in Wide-Band-Gap Semiconductors

A fundamental understanding of the mechanisms governing the behavior of defects and impurities is essential to control doping in semiconductors. Wide-band-gap semiconductors, in particular, often exhibit doping-related problems. We discuss how rst-principles theoretical techniques can be applied to the calculation of formation energies and concentrations of native defects and dopant impurities....
