• 一般注記: Crystal growth of spatially homogeneous In(x)Ga(1-x)As substrates, which has a tunable lattice matching between the substrate and the epilayer for InGaAs-based optoelectronic devices, is very difficult due to the considerable amount of convective flow on ground. This problem can be overcome, if the crystal growth is carried out in micro-gravity conditions and the starting material is chosen with particular specifications. The initial studies have indicated that the starting material is required to be cylindrically shaped polycrystalline InGaAs with a particular gradient in its compositional profile. This starting material has been grown and grinded to the required shape. In a view to analyze the compositional profile of this cylindrical polycrystalline starting material using a non-destructive method, some results of micro-Raman scattering studies are reported. Further, the effect of the surface condition on Raman results are also discussed, by comparing the results obtained from as-grinded and polished surfaces.; 資料番号: AA0032602007; レポート番号: NASDA-TMR-010016E
