摘要：
We have investigated the photoluminescence (PL) properties of Zn1-xMgxSe epilayers grown on GaAs substrates with different misorientation angles by molecular beam epitaxy. According to the data measured by PL and by electron-probe microanalysis, the Mg incorporation in the Zn1-xMgxSe epilayer decreases with increasing misorientation angle. In addition, the PL spectra showed that the full width at half maxima of the band-edge excitonic emission and the intensity of the defect-related donor-acceptor emission in Zn1-xMgxSe epilayers decreased appreciably when a substrate with a misorientation angle of 15 degrees was used.
