Outline of Final Research Achievements |
This project aims at the further exploration of the optical functionality of semiconductor quantum dots by developing a hybrid approach of substitutional doping and chemical doping. By performing detail structural and optical studies on boron and phosphorus codoped silicon quantum dots developed by our group, the effect of substitutional doping on the excess carriers inside quantum dots and energy level structure are investigated. In addition, the chemical doping is successfully demonstrated using molecular reductant and the photocatalytic reaction that cannot be achieved by solely substitutional doping, is demonstrated.
