초록

Thin GaInP 2 passivating films were deposited on isolated and close-packed arrays of colloidal InP/GaInP 2 core-shell nanocrystals (NC) using metalorganic chemical vapor deposition (MOCVD). The InP colloidal NCs were coated with 0.5-2.0 nm layer of GaInP 2 in solution to form core-shell NCs to prevent sintering of NC during the heating process. The NCs were then incorporated into the GaInP 2 matrix by the MOCVD growth technique. The results show that very strong electronic coupling between dots occurs in the complex composite when the distance between the core-shell NCs was reduced to ≥0.9 nm by using a hexylamine cap.
