Inserting an “atomic trap” for directional dopant migration in core/multi-shell quantum dots

Chun Chu,

Elan Hofman,

Chengpeng Gao

et al.

Abstract: Directional Mn dopant migration (outward/inward) was achieved by inserting a CdZnS “atomic trap” with a small size mismatch with dopants in core/multi-shell QDs. A larger initial substitutional site allows for active trapping and dopant migration.
