| Outline of Final Research Achievements |
Influence of indium supply on growth dynamics of Au-catalysed InGaAs nanowires was studied by in situ X-ray diffraction. We found that supplying indium along with gallium results in an interruption of nanowire growth, and that the nanowires are gradually buried in the layer part of InGaAs. Low temperature growth is effective to avoid this interruption and maintain the nanowire growth. Moreover, we found that the indium composition in nanowires was lower than the supplying ratio.
