W. 收藏  |  浏览/下载：22/0  |  提交时间：2013/03/25 Hexagonal MgxZn1-xO alloy layers with 0 &le 0.3 have been grown by plasma-assisted molecular beam epitaxy on sapphire (006) and Si (111) substrates. Their crystal structures are characterized by x-ray diffraction spectroscopy. The nonresonant and resonant Raman spectra were measured using 488 nm line from Ar+ laser  and 325 nm line from He-Cd laser by backscattering geometry. Four Raman modes (E2 high  LO  TO  multiphonon processes) were observed in the nonresonant Raman spectra of hexagonal MgxZn1-xO with different Mg contents. The optical phonon frequencies were found to display one-mode behaviour for all the samples since no separate ZnO- and MgO-like modes were observed. The long-wavelength frequencies of ZnO-like optical phonons measured in the resonant Raman spectra can be expressed as linear functions of x. These behaviours can be explained within a modified random-element-isodisplacement model (MREI). 2006 WILEY-VCH Verlag GmbH Co. KGaA.
