Fundamental science research at the CeNO is concentrated on theoretical and experimental investigations in nanoplasmonics – a field of nanooptics studying metal nanoparticles their complexes with nanostructured semiconductors and dielectrics. Areas of concentration include nanoplasmonic systems of gain, the so called spasers and nanolasers. Other directions of focus encompass the study of adiabatic nanofocusing of optical energy in tapered nanoplasmonic waveguides and ultrafast phenomena in nanoplasmonics, especially those in strong optical fields.
The research in this area concentrates on development of nanoplasmonic systems for biomedical diagnostics and treatment. One of the promising directions of research is devoted to utilizing active nanoplasmonic systems for diagnostics and laser therapy of cancers. Another is devoted to nanoplasmonic approaches to visualization in neurological and brain sciences.
Energy Generation and Conservation
Research in energy sciences at the Center is focused on nanoplasmonically enhanced photovoltaics and production of solar fuels. One of the original directions is to use adiabatic nanofocusing for high-efficiency solar energy conversion via plasmonically-generated hot electrons. A related direction is to use high-quality semiconductor nanostructures, in particular III-Nitrides, in combination with nanoplasmonic concentration of solar energy.
This research will concentrate in two directions. First, application of spasers as highly-efficient near-field sources for on-chip interconnects is developed. Second, use of gain nanoplasmonic system as active elements (“optical transistors”) for ultrafast information processing in the Petahertz frequency range is pursued.
Nanoplasmonic based sensors are being developed for detection and ultrasensing of various chemical and biological agents in the interest of health sciences, defense, and homeland security.
