We report, for the first time, epitaxial growth of high-quality ZnS films o
n sapphire and silicon substrates, using pulsed laser deposition. X-ray dif
fraction results show that at all growth temperatures from 200 degrees C to
680 degrees C, epitaxial wurtzite (002) ZnS films have been successfully g
rown on(10 (1) over bar 2) sapphire and (001) silicon substrates. X-ray dif
fraction data yield full width at half maximum 2 theta values of 0.13 degre
es for as-grown samples, compared with 2 theta values of 0.09 degrees and 0
.08 degrees for the bare sapphire and silicon substrates respectively.
