III-nitride based functional hybrid nanostructures

Important results from the project

This grant is aimed at establishing long-term collaboration with the Quantum Light and Matter Group at University of Southampton, England, which is a well-known center for photonics, condensed matter physics and the interaction of light and matter at the quantum level. Nanophotonics promises new advantages in fundamental physics and new futuristic applications in low power, ultra-small devices performing at the quantum edge. The goal is to investigate optical functionality of objects with a size scale where the wave nature of particles determines the physical behavior of the objects.

Expected long term effects

Nanophotonics will affect positively a wide range of technologies such as information processing, security, medicine and biotechnology. In the frame of the project novel colloidal nanodots (NDs) will be designed and fabricated on nitride-based semiconductor quantum wells. Depending on the size and shape, the optical emission from colloidal NDs can range from ultraviolet to infrared wavelengths, and hence these NDs can be used for fabrication of efficient white light emitters. The collaboration with the Quantum Light and Matter Group will result in a new expertise and in a strengthening of the existing competence in the field of nanophotonics. After the collaboration with the Quantum Light and Matter Group, the project leader will be able to develop this direction at Linköping University.

Approach and implementation

During the first year the work will be focused on sample design and fabrication and on verification of the sample design. During the second year: planning of optical experiments and adjustment of equipment for characterization of hybrid nanostructures. During the third year of the project: verification of theoretical models with experiments. Publishing of results.
