摘要

ptical properties of GaN_0.018As_0.982 quantum wells grown by either migration-enhanced epitaxy (MEE) or molecular beam epitaxy have been compared. MEE samples exhibit significantly enhanced photoluminescence (PL) intensity, reduced PL line width, and reduced PL low-energy tail, which could be correlated to better composition homogeneity.
