The chromium-doped ZnTe layers were grown by molecular beam epitaxy technol
ogy on the GaAs substrates. The metallic chromium was used as a dopant. The
characteristic emission of the Cr2+ ions that is incorporated into ZnTe ep
ilayers was obtained. However, the attempt of doping by CrI3 has shown that
the halides induce a deterioration of the surface morphology and are ineff
icient dopants for II-VI semiconductors. (C) 2001 American Vacuum Society.
