초록
The optical properties of III-V compound semiconductor structure was investgated by photoreflectance (PR). The results show two signals at 1.42 and 1.73eV. These are attributed to the bandgap energy of GaAs, AlGaAs, respectively. Also, AlGaAs region showed weak signal. This signal is attributed to carbon or si defect.
