New paper: Switchable Dissociation of Excitons bound at Strained CdTe/CdS Interfaces
In this paper we demonstrate CdSe/CdS seeded nanorods with a single CdTe tip at one end, which can be switched between a quickly deactivating off state and an on state that provides a long-lived electron for photo-catalysis or photovoltaics. Three properties are shown to contribute to the switchable exciton localisation in a synergistic manner: lattice distortion at the CdTe/CdS interface, Coulomb interaction, and size quantisation of the nanorods. The CdSe seed acts as a reporter for…
