Epitaxial layers of ZnSnAs2 were grown by molecular beam epitaxy on Si
and InP substrates. Growth conditions were investigated by varying th
e substrate temperature and the Sn, As, and Zn fluxes. The best morpho
logy and stoichiometry was obtained at T-s = 300-320 degrees C and the
Aux ratio of P-As4/P(Zn )similar to 1.5-4. The samples were evaluated
by secondary neutral mass spectroscopy, high resolution x-ray diffrac
tion, Raman spectroscopy, and atomic force microscopy. Single phase la
yers of ZnSnAs2 grown on InP(001) substrates show lattice mismatch of
-3.4 x 10(-4). (C) 1998 American Vacuum Society.
