Jm. Bluet et al., OPTICAL INVESTIGATION OF THICK 3C-SIC LAYERS DEPOSITED ON BULK SILICON BY CVD, DIAMOND AND RELATED MATERIALS, 6(10), 1997, pp. 1385-1387
Thick (up to 25 mu m) SiC layers deposited on silicon have been probed
by micro-Raman spectroscopy and infrared reflectivity measurement. Th
e Raman spectra collected on the edge of the sample show a large strai
n relaxation when moving from the interface region to the free surface
of the sample. The IR reflectivity measurements evidence a finite rou
ghness of the Si/SiC interface and about 10% dispersion in the layer t
hickness homogeneity. (C) 1997 Elsevier Science S.A.
