THE STRUCTURE OF BANDS DUE TO SILICON CARBIDE TRANSITIONS IN THE ENERGY REGION OF 4-35 еV

Abstract

The full spectral complex of optical functions of the 6H-SiC polytype was determined in the energy range from 0 to 35 eV. The spectra of ε2(E), - Imε-1, - Im(1+ε)-1 were decomposed into 15 simple bands. Main parameters of the bands were established including the maximum energy and oscillator strengths. The calculations were performed on the basis of the experimental reflectivity spectrum using the Kramers-Kronig relation and an improved nonparameteric method of the Argand diagrams.
