Bright CdSe/ZnSe nanowire-quantum dots for single photons emission

Semiconductor nanowires (NW) are appealing structures that allow designing quantum structure with unprecedented freedom. With NW, new type of quantum dot (QD) heterostructures (NW-QD) can be directly grown on defined positions without the necessity of self-assembly, as well as more complex structures such as coupled QDs or core-shell structure. However, the quantum confinement requires growing NW with very small lateral size (of the order o the Bohr radius) with high crystalline structure and clean surfaces (to prevent quenching of the exciton emission through non radiative recombination.
