About Kono Group

Research:

Our research is currently focused on the physics and applications of semiconductor nanostructures and quantum device structures. We use state-of-the-art spectroscopic techniques to study charge, spin, and vibrational dynamics in a variety of nanostructures. The impact of our research includes: increased understanding of the quantum states and dynamics of interacting, confined, or strongly driven electrons in nanostructures; new spectroscopy techniques; novel device concepts and implementations (especially towards all-optical switches and spin-based devices); establishment of the quantum nature of semiconductor-light interaction; progress towards the solid-state realization of quantum information processing, computation and communications; and provision of a controlled environment in which to address unanswered questions in many-body physics.
