Staff Scientist position in wide-bandgap optoelectronics

Information about the research group and the project
The Photonics Laboratory at the Department of Microtechnology and Nanoscience (MC2), with about 35 researchers, is working on optoelectronics, ultrafast optics and fiber-optical communication. We have a strong research focus on blue and ultraviolet-emitting vertical-cavity surface-emitting lasers (VCSELs), photonic-crystal surface emitting lasers (PCSELs), light-emitting diodes (LEDs), and resonant-cavity LEDs (RCLEDs). We have expertise and infrastructure in device design and simulation, laser fabrication, as well as material and device characterization. We have developed a novel thin-film lift-off process for AlGaN-materials based on electrochemical etching, which allows integration of III-nitride thin films with various photonic structures, such as dielectric cavities with improved quality factor. These have enabled us to demonstrate the world’s first blue vertical-cavity surface-emitting lasers (VCSEL) with a high-contrast grating for polarization pinning, thin-film flip-chip UVB LEDs and the shortest emission wavelength from an optically pumped VCSEL at 310 nm. We are a team of currently eight persons and to keep continuity and ensure hands-on knowledge transfer we are now expanding our team with a permanently employed staff scientist to push all our topics forward in the best way possible.  

Major responsibilities and information about the position
In our team your major responsibility will be to supervise and guide the research and development of PCSELs, VCSELs, (RC)LEDs, and potentially other device types from III-nitride materials emitting in the blue and ultraviolet. This will require further development of fabrication process flows and electrochemical etching, as well as exploration of tunnel junctions for electrically injected VCSELs. Your work will include guiding and supervising PhD students and Postdocs, both on a theoretical and experimental level. You will ensure continuity and hands-on knowledge transfer between successive group members. You are also expected to initiate new research projects in line with the existing ones and write research proposals to attract funding. The work will be conducted in close collaboration with external partners who provide the epitaxial material. In this position, teaching is optional.

Qualifications
You must have a PhD degree in Physics, Material Science, or Photonics, and a strong track record covering research in semiconductor physics, III-nitride materials, photonics, as well as optoelectronic device fabrication along with characterization. Strong merits will be hands-on experience with (photo)electrochemical etching of III-nitrides, complex process flows, optical and electrical characterization of III-nitride lasers as well as implementations of tunnel junctions for blue or ultraviolet light-emitting diodes and lasers. Knowledge on optical and electronic device simulations or epitaxial growth of III-nitrides is also regarded as an asset. We value personal qualities such as enthusiasm, ability to drive and conclude projects independently, creative thinking and problem-solving ability. Good teamwork and social abilities are also appreciated. Excellent communication skills in spoken and written English are necessary. 

Contract terms
This position is a full-time permanent employment.
