Title:
III族窒化物半導体薄膜およびIII族窒化物半導体発光素子
Document Type and Number:
Japanese Patent JP4888857
Kind Code:
B2
Abstract:
A group III nitride semiconductor thin film and a group III nitride semiconductor light emitting device using the same. The group III nitride semiconductor thin film includes a substrate with a concave and convex portions formed thereon; a buffer layer formed on the substrate and made of a group III nitride; and an epitaxial growth layer formed on the buffer layer and made of (11-20) plane gallium nitride. The group III nitride light emitting device includes the group III nitride semiconductor thin film. The present invention allows a high quality a-plane group III nitride semiconductor thin film and a group III nitride semiconductor light emitting device using the same.
