| Abstract(in English) | Recently InN-based III-nitride semiconductors have attracted much attention as a promising material system for photonic devices operating in optical communication wavelength. Up to now, we have studied on the growth of AlInN ternary alloys and investigated on their structural and optical properties. It was found that the AlInN ternary alloys in the mid-composition tend to have a poor crystallinity because of the phase separation arising from the large immiscibility between InN and AlN. In this report, we investigated on the detailed crystalline and optical properties of AlInN ternary alloys in the mid-composition grown by RF-MBE using CL measurements. The AlInN films grown at higher temperatures have the CL spectra indicating their poor crystallinity. On the other hand, the AlInN films grown at lower temperatures have the CL spectra those peek is lower in energy than their bandgaps in spite of their crystalline uniformity. This broadening of the CL spectra attributed to the effects of point defects at the boundary of three-dimensional islands. |
