内容記述タイプ | Abstract | |||||
内容記述 | We investigated the radiative recombination properties of semi-polar (11̅01)GaN films grown on patterned (001)Si substrate by using photoreflectance (PR) and photoluminescence (PL) spectroscopies. The X-ray diffraction (XRD) method was also used for investigating strain content. Estimated bandgap energy (Eg) by Kramers-Kronig transformation of PR spectrum showed about 35 meV lower energy side than that of polar (0001)GaN. It was found that the strain of growth direction (=[111]Si) did not exist from the XRD 2- scan. Therefore, reduction of Eg may be caused by the tensile strain along the [11̅0]Si or [112̅-]Si direction. From the low temperature PL and PR measurements, we could confirm the several radiative peaks caused by donor-bound exciton, acceptor-bound exciton, and donor-to-acceptor pair recombination. | |||||
