Improving crystal quality of Er-doped Gd₂O₃ grown on a Si(111) substrate by inserting a bifunctional GdO_x layer

Abstract

We developed a growth technique that improves the crystallinity and optical properties (photoluminescence intensity and lifetime) of Er-doped Gd2O3 (Er:Gd2O3) on Si (111) substrate. Deposition of thin (7.5 Å thick)...
