Abstract

Yellow/amber (570-600 nm) emitting InxGa1-xN/AlyGa1-yN/GaN multiple quantum wells (QWs) have been grown by metal organic chemical vapor deposition on GaN-on- sapphire templates. When the (Al,Ga)N thickness of the barrier increases, the room temperature photoluminescence is red-shifted while its yield increases. This is attributed to an increase of the QW internal electric field and an improvement of the material quality due to the compensation of the compressive strain of the InxGa1-xN QWs by the AlyGa1-yN layers, respectively.
