Zinc sulfide (ZnS) thin films were grown on (100)Si substrates from so
lution with the successive ionic layer adsorption and reaction (SILAR)
method. Aqueous solutions of ZnCl2 and Na2S were used as precursors.
The morphological development of the films with increasing number of S
ILAR cycles was monitored ex situ by atomic force microscopy (AFM) ope
rated in tapping mode. Their roughness increased vs. the growth cycles
. AFM studies on (100)Si substrates treated with Na2S solution reveale
d that the dissolution of the silicon substrates is a process competin
g with the thin film growth and has to be considered when interpreting
the AFM images. (C) 1998 Elsevier Science B.V. All rights reserved.
