Plasmon-based light-emitting diodes project (2.01 MDKK) is supported by the Danish Ministry of Higher Education and Science through FTP postdoc program.
Project description:
Light-emitting diodes (LEDs) directly convert electrical energy into light and emerge as a lighting technology of the future. The brightness of the current white LED is limited by the low efficiency in the green and yellow wavelength region. This project explores the possibility of using metallic nanostructures to improve the overall efficiency of a green LED integrated in a planar electrically driven system with a high index substrate. Exploiting such plasmon enhanced green LEDs with the potential of massive energy savings may lead to the ultimate solution for next generation lighting. This project is about to model, understand, and demonstrate super bright and high efficient green GaN-LED by using metallic nanostructures, including ordered and disordered particle arrays, and metallic rods based optical nano-antennas, to improve the emission and light extraction from the active layers.
