Abstract
A III-nitride film, grown on an m-plane substrate, includes multiple quantum wells (MQWs) with a barrier thickness of 27.5 nm or greater and a well thickness of 8 nm or greater. An emission wavelength can be controlled by selecting the barrier thickness of the MQWs. Device fabricated using the III-nitride film include nonpolar III-nitride light emitting diodes (LEDs) with a long wavelength emission.
