Highly efficient carrier multiplication in inverted CdSe/HgSe quantum dots mediated by magnetic impurities

QD synthesis and doping with manganese

We started our work on QD synthesis by optimizing undoped core/shell CdSe/HgSe/ZnS QDs. Bulk HgSe has a negative bandgap of –0.24 eV (ref. ²²). In the case of quantum-confined nanostructures, this…
