PhD Scholarship in Photonics Engineering

A PhD scholarship is available in Photonics Engineering at Technical University of Denmark. This scholarship is available for all students around the world. Applicants should apply before April 01, 2015.

Light-emitting diodes (LEDs) light source is emerging as the future market leader in both indoor and outdoor lighting due to its high energy efficiency, good light quality, long lifetime, and good technical functionality like being a transmitter for visible light communication. This project is going to explore a new type of white LED, which uses fluorescent silicon carbide (f-SiC) as the wavelength conversion material. Compared to the widely used phosphors, f-SiC only contains earth-abundant material, is very robust, and a better substrate than Sapphire for the epitaxial GaN growth on top.

Therefore, the new white LED based on f-SiC is going to further reduce the energy consumption and CO2 emission. In this project, the full potential of this new type of LED will be explored in different levels of materials, devices and modules oriented for applications in general lighting through the collaboration of top scientists from Europe and China, with involvement of industrial partners. It is expected that the new f-SiC LED will promote the adoption of the LED technology.

Application Requirements
- The selected PhD student will participate in a project team of 1 postdoc and 2 PhD students hired specifically on the project, in addition to the participating senior staff. The student will specifically be in charge of the demonstration of the high-emission-efficiency fluorescent SiC in collaboration with Linköping University and University of Erlangen-Nürnberg.

The candidate is thus expected to:
- Interact strongly with Linköping University and spend a period of about 6 months there for fluorescent SiC growth by using fast sublimation growth process.
- Characterize the material by using photoluminescence, SIMS, X-ray diffraction, etc. for optimization of the material growth.
- Build setup for emission efficiency measurement.
- Candidates should preferably have a master degree in material science or equivalent. In addition we expect candidates to.
- Be fluent in English.
- Be willing to work in close collaboration with an internal project team and with external international partners.
- Be willing to supervise master and bachelor students.
- Have good experience with light-emitting semiconductor materials
