| 英文摘要 | Triple-axis x-ray diffraction (txrd) and photoluminescence (pl) spectra are used to assess the influence of the ratio of tmin flow to group iii flow on structural defects, such as dislocations and interface roughness, and optical properties of multiple quantum wells(mqws). in this paper the mean densities of edge and screw dislocations in ingan/gan mqws are obtained by w scan of every satellite peak of (0002) symmetric and (1012) asymmetric diffractions. at the same time, the interface roughness is measured by the radio of the full width at half maximum of satellite peaks to the peak orders. the experimental results showed that the density of dislocation, especially of edge dislocation, and interface roughness increase with the increase of the ratio, which leads to the decrease of pl properties. it also can be concluded that the edge dislocation acts as nonradiative recombination centers in ingan/gan mqws. also noticed is that the variation of the ratio has more influence on edge dislocation than on screw dislocation. |
