Agd. Larocque et al., X-RAY PHOTOELECTRON-SPECTRA OF ADHESION-ENHANCED A-SI-H ON STAINLESS-STEEL INDUCED BY PLASMA TREATMENTS, Journal of non-crystalline solids, 230, 1998, pp. 59-62
An investigation by X-ray photoelectron spectroscopy (XPS) of adhesion
mechanisms of a-Si:H films on stainless steel substrates after hydrog
en (H-2), nitrogen (N-2) and ammonia (NH3) plasma treatments of the su
rface is presented. It is shown that adhesion is increased by N-2 trea
tment. This effect is related to chemical bonding states at the interf
ace. The improvement is attributed to the formation of silicon nitride
at the interface and to the existence of Fe-Fe metallic bonds which c
ontribute to a hardening of the substrate. (C) 1998 Elsevier Science B
