I am interested in the atomic-like properties of strongly confined excitons in semiconductor nanostructures. At the University of Rochester, we study InAs quantum dots through low-temperature non-resonant and resonant spectroscopy. When incorporated into a diode-like heterostructure, the ground-state charge can be tuned. In addition, InAs quantum dots have strong polarization selection rules. They have potential for use as qubits, specifically a spin-photon interface due to optical spin-pumping of the negatively charged exciton in a magnetic field.
