A detailed piezoreflectance (PzR) study of an Fe-containing silicon carbon
nitride crystalline film in the temperature range between 15 and 580 K was
performed. From the line shape fit of the PzR spectra, the impurity to band
and the direct band-to-band transition energies which are denoted as E-i a
nd E-g(d), respectively, at various temperatures were accurately determined
. The parameters that describe the temperature dependence of E-i and E-g(d)
are evaluated and discussed. (C) 2000 American Institute of Physics. [S002
