Abstract
We have applied photoluminescence excitation spectroscopy of the free-excit on related emission in 6H-SiC for studying the absorption edge. Detailed co mparison with the conventional techniques, absorption measurements and wave length modulated spectroscopy, is carried out, and our results are compared with those obtained from these techniques. A qualitative model of the abso rption mechanism is proposed in order to understand the appearance of peaks in the PLE spectra. (C) 1999 Elsevier Science S.A. All rights reserved.
