ZnO epitaxial layers grown on GaAs(111)B substrates by plasma assisted MBE with different O/Zn flux ratios are characterized by photoluminescence (PL), X-ray diffraction (XRD) θ –2θ scan, ω scan, and reciprocal lattice mapping. Low temperature PL spectra are dominated by bound exciton bands at 3.360 eV and 3.330 eV. The 3.360 eV band is strong in samples grown under Zn-rich cindition and the 3.330 eV band is strong in samples grown under O-rich condition. The epitaxial orientation relationship is ZnO(0001)//GaAs(111) and ZnO[11-20]//GaAs [01-1] irrespective of the O/Zn flux ratio. The ZnO c-axis tilts by 0.2° ∼ 0.3° from the GaAs [111] axis toward 〈1-10〉 or 〈2-1-1〉 direction. (© 2006 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)
