3d lattices of core/shell ge/mn quantum dots in an alumina matrix: structure, fabrication, and photo-electrical properties

HIGHLIGHTS

• What: The authors show a well-achieved formation of the 3D regular lattices of Ge-core Mn-rich shell quantum dots which were achieved by self-assembled growth mode. This research showed that the Ge QDs embedded in alumina (Al2 O3 ) matrices show very strong confinement effects, but, at the same time, there is one noteworthy problem, namely the oxidation of Ge. The study showcases the production of thin-film materials comprising Ge-core and Mn-rich shell QDs embedded within an amorphous alumina matrix. The authors aimed to demonstrate that it is possible to tune the . . .
