G. Cicala et al., PLASMA DEPOSITION OF AMORPHOUS SIC-H,F ALLOYS FROM SIF4-CH4-H-2 MIXTURES UNDER MODULATED CONDITIONS, Journal of applied physics, 79(11), 1996, pp. 8856-8858
Fluorinated and hydrogenated amorphous silicon-carbon alloys (n-SiC:H,
F) are produced by glow discharge decomposition of SiF4-CH4-H-2 mixtur
e. Small amount of CH4 in SiF4-H-2 mixture are enough to produce silic
on carbon alloys having optical gap ranging between 1.8 and 2.6 eV. Ma
terials, having 1.95 eV band gap and exhibiting optoelectronic propert
ies typical of state of art a-SiC:H, are deposited under plasma modula
tion conditions. (C) 1996 American Institute of Physics.
