ABSTRACT:
Disclosed herein is a high-quality group III-nitride semiconductor thin film and group III-nitride semiconductor light emitting device using the same. To obtain the group III-nitride semiconductor thin film, an AlInN buffer layer is formed on a (1-102)-plane (so called r-plane) sapphire substrate by use of a MOCVD apparatus under atmospheric pressure while controlling a temperature of the substrate within a range from 850 to 950 degrees Celsius, and then, GaN-based compound, such as GaN, AlGaN or the like, is epitaxially grown on the buffer layer at a high temperature. The group III-nitride semiconductor light emitting device is fabricated by using the group III-nitride semiconductor thin film as a base layer.
