PhD in Novel Light-Emitting Diodes based on Fluorescent SiC

jobbeskrivelse:
Department of Photonics Engineering at the Technical University of Denmark is seeking a candidate for a 3-year scholarship in the field of light-emitting diodes (LED). The position is funded by the project “A new type of white light-emitting diode using fluorescent silicon carbide ” (LEDSiC). Summary of the project LEDSiC 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. Responsibilities and tasks 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-efficiency fluorescent SiC based white LED. The candidate is thus expected to •Interact strongly with Institute of Semiconductors, Chinese Academy of Sciences and spend a period of about 6 months there for GaN MOCVD growth on fluorescent SiC substrate •Fabricate the LED devices in the state-of-the-art cleanroom at Danchip, including GaN etching, electrode deposition etc. •Characterize the LED devices in terms of IV curve, IP curve, efficiency, color rendering index etc. Qualifications Candidates should preferably have a master degree in photonics 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 cleanroom fabrication like photolithography, reactive ion etching, thin film deposition etc. •Have some knowledge of LED We offer We offer an interesting and challenging job in an international environment focusing on education, research, and innovation, which contribute to enhancing the economy and improving social welfare. We strive for academic excellence, collegial respect and freedom tempered by responsibility. The Technical University of Denmark (DTU) is a leading technical university in northern Europe and benchmarks with the best universities in the world. Salary and terms of employment The appointment will be based on the collective agreement with the Confederation of Professional Associations. The allowance will be agreed with the relevant union. The period of employment is 3 years, starting from July 1, 2015 or as soon as possible thereafter. Assessment The assessment of the applicants will be made by Associate Professor Haiyan Ou.
